Description
This function retrieves the specified result of the specified type for a point, edge, stripe, or circle from a measurement marker buffer or a measurement result buffer. Measurement marker buffers hold the results of an MmeasFindMarker operation, while measurement result buffers hold the results of an MmeasCalculate operation. Depending on the buffer you are using, you must call either MmeasFindMarker or MmeasCalculate prior to calling MmeasGetResult; otherwise, you will get an incorrect result.
If you are using a multiple-occurrence marker, MmeasGetResultSingle returns the specified result for a single occurrence, which you must specify with the ResultIndex parameter. To return results for all occurrences, use MmeasGetResult.
If your target image was associated with a camera calibration context, positional and dimensional results are, by default, returned with respect to the relative coordinate system of the image. Otherwise, these results are returned in pixels, relative to the top-left pixel in the target image.
If your target image was associated with a camera calibration context and you want to retrieve positional and dimensional results in pixel units, use MmeasSetMarker for a measurement marker buffer, or MmeasControl for a measurement result buffer, with M_RESULT_OUTPUT_UNITS set to M_PIXEL. If you set M_RESULT_OUTPUT_UNITS to M_WORLD without specifying a calibrated image in which to calculate the results, MmeasGetResultSingle will generate an error.
For certain result types, Aurora Imaging Library returns one value for an edge marker, and two values for a stripe marker. In these cases, for an edge marker, Aurora Imaging Library returns the result to FirstResultArrayPtr; SecondResultArrayPtr must be set to M_NULL.
When retrieving a result for a stripe marker, result types can return one general result for the stripe, a result for both edges of the stripe, or a result for one edge of the stripe. To return the result for one edge of the stripe, you must specify the edge using the combination value M_EDGE_FIRST or M_EDGE_SECOND.
When retrieving non-positional results for both edges of a stripe marker, Aurora Imaging Library returns the results for the first edge to FirstResultArrayPtr and for the second edge to SecondResultArrayPtr. When retrieving non-positional results for one edge of the stripe, Aurora Imaging Library always returns the result to FirstResultArrayPtr.
When retrieving positional results for a stripe, Aurora Imaging Library returns the results for the X-coordinate of the stripe to FirstResultArrayPtr and the Y-coordinate of the stripe to SecondResultArrayPtr. When retrieving positional results for one edge of the stripe, Aurora Imaging Library returns the X-coordinate to FirstResultArrayPtr and the Y-coordinate to SecondResultArrayPtr. You can set FirstResultArrayPtror SecondResultArrayPtrtoM_NULL to retrieve only one coordinate.

Parameter Associations
For any type of marker (measurement marker buffer) or a measurement result buffer
To retrieve a result from any type of marker (measurement marker buffer), or from a measurement result buffer, ResultType can be set to one of the values specified in the table below. If you are getting results from a measurement result buffer, and you are using two multiple-occurrence markers that have a different number of occurrences, Aurora Imaging Library uses the fewest number of occurrences to calculate results (MmeasCalculate).
M_NUMBER
Retrieves the number of points, edges, stripes, or circles measured. Note that edges, stripes, and circles are searched for, but points are placed manually. For circle markers, M_NUMBER will never return a value greater than one, since circles cannot be defined as a multiple-occurrence marker. After a call to the MmeasFindMarker function, this number is equal to the number of occurrences of a marker found in the search region. After a call to the MmeasCalculate function, this number is equal to the smallest number of occurrences held in either marker involved in the calculation.
For an edge or stripe marker (measurement marker buffer) or a measurement result buffer
To retrieve a result from an edge or stripe marker (measurement marker buffer), or from a measurement result buffer, ResultType can be set to one of the values specified in the table below. If you are getting results from a measurement result buffer, and you are using two multiple-occurrence markers that have a different number of occurrences, Aurora Imaging Library uses the fewest number of occurrences to calculate results (MmeasCalculate).
M_ANGLE
Retrieves the angle of the edge for the marker occurrence, in degrees. The angle is relative to the output coordinate system specified using M_RESULT_OUTPUT_UNITS with either MmeasSetMarker (for a measurement marker buffer) or MmeasControl (for a measurement result buffer). If retrieved from a measurement marker buffer, M_ANGLE returns the angle of the line measured for the edge. For a stripe marker, this line follows the center of the stripe and is calculated as the mean of the lines following its edges. If the result is requested for a specific edge of the stripe, using the combination value M_EDGE_FIRST or M_EDGE_SECOND, the angle of the first or second edge is returned, respectively. If retrieved from a measurement result buffer, M_ANGLE returns the angle of the line joining the two marker occurrences, relative to the positive X-axis. An angle interpreted with respect to the pixel coordinate system is always measured counter-clockwise. For information on the angle's direction of rotation when interpreting the angle with respect to the relative coordinate system, see Angle convention in Aurora Imaging Library.
M_LINE_A
Retrieves the coefficient A of the line equation, for the marker occurrence. The line equation is of the general form, _Ax_ + _By_ + _C_ = 0. If retrieved from an edge marker (measurement marker buffer), M_LINE_A returns the coefficient A of the line measured for the edge. For a stripe marker, this line follows the center of the stripe, and is calculated as the mean of the lines following its edges. If the result is requested for a specific edge of the stripe, using the combination value M_EDGE_FIRST or M_EDGE_SECOND, the coefficient A of the line equation of the first or second edge, respectively, is returned. If retrieved from a measurement result buffer, M_LINE_A returns the coefficient A of the line joining the two markers.
M_LINE_B
Retrieves the coefficient B of the line equation, for the marker occurrence. The line equation is of the general form, _Ax_ + _By_ + _C_ = 0. If retrieved from an edge marker (measurement marker buffer), M_LINE_B returns the coefficient B of the line measured for the edge. For a stripe marker, this line follows the center of the stripe, and is calculated as the mean of the lines following its edges. If the result is requested for a specific edge of the stripe, using the combination value M_EDGE_FIRST or M_EDGE_SECOND, the coefficient B of the line equation of the first or second edge, respectively, is returned. If retrieved from a measurement result buffer, M_LINE_B returns the coefficient B of the line joining the two markers.
M_LINE_C
Retrieves the coefficient C of the line equation, for the marker occurrence. The line equation is of the general form, _Ax_ + _By_ + _C_ = 0. If retrieved from an edge marker (measurement marker buffer), M_LINE_C returns the coefficient C of the line measured for the edge. For a stripe marker, this line follows the center of the stripe, and is calculated as the mean of the lines following its edges. If the result is requested for a specific edge of the stripe, using the combination value M_EDGE_FIRST or M_EDGE_SECOND, the coefficient C of the line equation of the first or second edge, respectively, is returned. If retrieved from a measurement result buffer, M_LINE_C returns the coefficient C of the line joining the two markers.
For any type marker (measurement marker buffer)
To retrieve a result from any type of marker (measurement marker buffer), ResultType can be set to one of the values specified in the table below.
M_POSITION
Retrieves the X- and Y-coordinates of the position, for the marker occurrence. For point markers, the position refers to the X- and Y-coordinates specified using MmeasSetMarker with M_POSITION. For edge markers, the position refers to the X- and Y-coordinates of the edge's maximum edgevalue (highest edge peak) along the center of the search region. For stripe markers, the position refers to the X- and Y-coordinates at the center of a theoretical line between the position (maximum edgevalue) of the stripe's two outermost edges. If you use M_EDGE_FIRST or M_EDGE_SECOND, you will get the X- and Y-coordinates of that edge's maximum edgevalue (highest edge peak). For circle markers, the position refers to the X- and Y-coordinates at the circle's center.
M_VALID_FLAG
Retrieves whether the marker was found, or that the coordinates of a point marker (MmeasAllocMarker with M_POINT) are set to a valid position.
| Value | Description |
|---|---|
M_FALSE | Specifies that the marker was not found. |
M_TRUE | Specifies that the marker was found. |
For an edge, stripe, or circle marker (measurement marker buffer)
To retrieve a result from an edge, stripe, or circle marker (measurement marker buffer), ResultType can be set to one of the values specified in the table below.
M_FIT_ERROR_MAX
Retrieves the maximum distance from a subedge to the fitted line equation (for edge or stripe markers) or to the fitted circle (for circle markers), for the marker occurrence. This distance is called the maximum fit error. If you did not specify subregions (for edges or stripes), M_FIT_ERROR_MAX returns 0. Note that circles always have subregions.
M_NUMBER_OF_OUTLIERS
Retrieves the number of subedges considered outliers, for the marker occurrence. Outliers are subedges within the search region that do not contribute to marker's fit operation since they are considered to be too far away from the general distribution of subedges. The number of outliers corresponds to the number of fitted subedges subtracted from the number of subregions.
M_SEARCH_REGION_WAS_CLIPPED
Retrieves whether the search region was clipped. This value is only useful if you enabled clipping (MmeasSetMarker with M_SEARCH_REGION_CLIPPING).
| Value | Description |
|---|---|
0 | Specifies that the search region was not clipped. |
1 | Specifies that the search region was clipped. |
M_SUB_EDGES_MARKER_INDEX
Retrieves the index on which each subedge is located, for the marker occurrence. If a subedge is not found in a subregion, an arbitrary number is returned. Use M_SUB_EDGES_WEIGHT to determine if a subedge was actually found. This result is useful when retrieving subedge-type of results for a multiple-occurrence marker. For example, you can use the index to separate, by marker, the values obtained with M_SUB_EDGES_POSITION and M_SUB_EDGES_WEIGHT.
| Value | Description |
|---|---|
M_EDGE_FIRST | Specifies that the edge is the first edge in the stripe. |
M_EDGE_SECOND | Specifies that the edge is the second edge in the stripe. |
M_SUB_EDGES_POSITION
Retrieves the X- and Y-coordinates of the subedges, for the marker occurrence. If a subedge is not found in a subregion, the X- and Y- positions will be arbitrary numbers. Use M_SUB_EDGES_WEIGHT to determine whether a subedge was found.
M_SUB_EDGES_WEIGHT
Retrieves the weight of the subedges, for the marker occurrence. The weight indicates whether a subedge was found in the subregion. Found subedges are used to calculate the fit, angle, and line equation values.
| Value | Description |
|---|---|
0 | Specifies that the subedge was not found. |
1 | Specifies that the subedge was found. |
M_SUB_REGIONS_NUMBER_USED
Retrieves the number of subregions used. Note that if you did not specify multiple subregions (MmeasSetMarker with M_SUB_REGIONS_NUMBER), Aurora Imaging Library will internally use three to perform certain measurements.
For an edge or stripe marker (measurement marker buffer)
To retrieve a result from an edge or stripe marker (measurement marker buffer), ResultType can be set to one of the values specified in the table below, unless otherwise specified.
M_BOX_ANGLE_FOUND
Retrieves the angle found for the box search region when the angle is internally determined by Aurora Imaging Library. In this case, you must have specified M_ANY as the angle of the box search region (MmeasSetMarker with M_BOX_ANGLE) or enabled an angular search (M_BOX_ANGLE_MODE set to M_ENABLE). An angle interpreted with respect to the pixel coordinate system is always measured counter-clockwise. For information on the angle's direction of rotation when interpreting the angle with respect to the relative coordinate system, see Angle convention in Aurora Imaging Library.
M_BOX_CORNER_BOTTOM_LEFT
Retrieves the coordinates of the bottom-left corner of the marker's box search region. If the box search region was rotated using MmeasSetMarker with M_BOX_ANGLE or from an angular search, the result will take that rotation into account.
M_BOX_CORNER_BOTTOM_RIGHT
Retrieves the coordinates of the bottom-right corner of the marker's box search region. If the box search region was rotated using MmeasSetMarker with M_BOX_ANGLE or from an angular search, the result will take that rotation into account.
M_BOX_CORNER_TOP_LEFT
Retrieves the coordinates of the top-left corner of the marker's box search region. If the box search region was rotated using MmeasSetMarker with M_BOX_ANGLE or from an angular search, the result will take that rotation into account.
M_BOX_CORNER_TOP_RIGHT
Retrieves the coordinates of the top-right corner of the marker's box search region. If the box search region was rotated using MmeasSetMarker with M_BOX_ANGLE or from an angular search, the result will take that rotation into account.
M_BOX_EDGEVALUES
Retrieves the edgevalues of the marker's box search region. Aurora Imaging Library establishes edgevalues by applying a first derivative filter to the search region's intensity profile and normalizing the output according to the number of pixels and the maximum pixel value possible. To establish the intensity profile, Aurora Imaging Library projects the pixels bounded by the two-dimensional search region (or each subregion) into a one-dimensional pixel intensity summation, which is performed vertically or horizontally, depending on the search region's origin and search direction.
M_BOX_EDGEVALUES_NUMBER
Retrieves the number of edgevalues that M_BOX_EDGEVALUES returns. This value corresponds to the number of pixels along the width or height of the box search region, depending on the search region's origin and search direction.
M_DISTANCE_FROM_BOX_ORIGIN
Retrieves the position, as a distance value relative to the origin of the box search region, for the marker occurrence.
M_EDGE_CONTRAST
Retrieves the grayscale difference between the start (M_EDGE_START) and end (M_EDGE_END) of the intensity transition from which the edge is established, for the marker occurrence.
M_EDGE_END
Retrieves the X- and Y-coordinates of the end of the edge (that is, the end of the intensity transition from which the edge is established), for the marker occurrence. For a stripe marker, the coordinates representing the average value of end positions is returned unless otherwise specified by the combination value M_EDGE_FIRST or M_EDGE_SECOND. In the intensity profile calculated for a search region, M_EDGE_START represents the first significant slope used to establish the edge, while M_EDGE_END represents the first significant slope in the opposite direction used to establish the edge. Depending on the search region's origin and search direction, the edge's start and end can be on either side of the edge. [Image: EdgedetectionReference.png] To retrieve the minimum and maximum position of the edge peak of the marker, use M_EDGEVALUE_PEAK_POS_MIN and M_EDGEVALUE_PEAK_POS_MAX.
M_EDGE_INSIDE
Retrieves the number of edges located between the two exterior edges of a stripe, for the marker occurrence. This result only applies to stripes.
M_EDGE_START
Retrieves the X- and Y-coordinates of the start of the edge (that is, the start of the intensity transition from which the edge is established), for the marker occurrence. For a stripe marker, the coordinates representing the average value of start positions is returned unless otherwise specified by the combination value M_EDGE_FIRST or M_EDGE_SECOND. In the intensity profile calculated for a search region, M_EDGE_START represents the first significant slope used to establish the edge, while M_EDGE_END represents the first significant slope in the opposite direction used to establish the edge. Depending on the search region's origin and search direction, the edge's start and end can be on either side of the edge. [Image: EdgedetectionReference.png] To retrieve the minimum and maximum position of the edge peak of the marker, use M_EDGEVALUE_PEAK_POS_MIN and M_EDGEVALUE_PEAK_POS_MAX.
M_EDGE_STRENGTH
Retrieves the greatest edgevalue of the edge, for the marker occurrence. The greatest edgevalue of an edge is considered to be its edge strength.
M_EDGE_WIDTH
Retrieves the distance between the start (M_EDGE_START) and end (M_EDGE_END) of the intensity transition from which the edge is established, for the marker occurrence. To retrieve the width of the edge established by the edge peak of the marker, use M_EDGEVALUE_PEAK_WIDTH.
M_EDGEVALUE_PEAK_CONTRAST
Retrieves the grayscale difference of the intensity transition between the first zero edgevalues on both sides of the established edge peak (before M_EDGEVALUE_PEAK_POS_MIN, and after M_EDGEVALUE_PEAK_POS_MAX), for the marker occurrence. Note that some images might never have a zero edgevalue, in which case you should use M_EDGE_CONTRAST for a more meaningful result.
M_EDGEVALUE_PEAK_POS_MAX
Retrieves the X- and Y-coordinates of the maximum position of the edge peak (that is, the maximum edgevalue along the first derivative representation of the intensity profile), for the marker occurrence. For a stripe marker, the coordinates representing the average value of maximum positions is returned unless otherwise specified by the combination value M_EDGE_FIRST or M_EDGE_SECOND. To establish the maximum and minimum positions of the edge peak, Aurora Imaging Library considers the portion of the peak that contains the maximum edgevalue, and that satisfies the M_EDGEVALUE_MIN and M_EDGEVALUE_VAR_MIN constraints set using MmeasSetMarker. That is, the peak must dip, on both sides, below either the minimum edgevalue threshold (M_EDGEVALUE_MIN) or the local edgevalue threshold established by subtracting M_EDGEVALUE_VAR_MIN from the peak's summit, whichever is highest. [Image: EdgedetectionEdgeValueMinAndVarMINReference.png] Depending on the search region's origin and search direction, the maximum and minimum position can be on either side of the edge peak's summit. Note that you can also retrieve different start and end positions of the edge using M_EDGE_START and M_EDGE_END.
M_EDGEVALUE_PEAK_POS_MIN
Retrieves the X- and Y-coordinates of the minimum position of the edge peak (that is, the minimum edgevalue along the first derivative representation of the intensity profile), for the marker occurrence. For a stripe marker, the coordinates representing the average value of minimum positions is returned unless otherwise specified by the combination value M_EDGE_FIRST or M_EDGE_SECOND. To establish the minimum and maximum positions of the edge peak, Aurora Imaging Library considers the portion of the peak that contains the maximum edgevalue, and that satisfies the M_EDGEVALUE_MIN and M_EDGEVALUE_VAR_MIN constraints set using MmeasSetMarker. That is, the peak must dip, on both sides, below either the minimum edgevalue threshold (M_EDGEVALUE_MIN)or the local edgevalue threshold established by subtracting M_EDGEVALUE_VAR_MIN from the peak's summit, whichever is highest. [Image: EdgedetectionEdgeValueMinAndVarMINReference.png] Depending on the search region's origin and search direction, the maximum and minimum position can be on either side of the edge peak's summit. Note that you can also retrieve different start and end positions of the edge using M_EDGE_START and M_EDGE_END.
M_EDGEVALUE_PEAK_WIDTH
Retrieves the distance between the minimum (M_EDGEVALUE_PEAK_POS_MIN) and maximum (M_EDGEVALUE_PEAK_POS_MAX) position of the edge peak (that is, the minimum and maximum positions of the edgevalue along the first derivative representation of the intensity profile), for the marker occurrence. To retrieve the width of the edge instead of the width of the edge peak, use M_EDGE_WIDTH.
M_LENGTH
Retrieves the length of the side of the search region perpendicular to the search direction. This is useful to retrieve the number of pixels that were projected into a single value of the intensity profile without having to find M_ORIENTATION first.
M_LINE_END_POINT_FIRST
Retrieves the X- and Y-coordinates of the first intersection point, for the marker occurrence, between the edge's mean line and the box search region. For a stripe marker, the mean line is the mean of the lines following its two edges. If you request this result for a specific edge of a stripe, using the combination value M_EDGE_FIRST or M_EDGE_SECOND, M_LINE_END_POINT_FIRST will return the first intersection point of the line following the specified edge and the box search region. If the box search region was rotated using MmeasSetMarker with M_BOX_ANGLE or from an angular search, the intersection will take that rotation into account. For vertical edges, the first intersection point is typically at the top of the box search region, while for horizontal edges the first intersection point is typically on the right of the box search region. Note that the intersection point that is considered to be the first or second (M_LINE_END_POINT_SECOND) can change depending on the edge's angle and whether the box search region is rotated.
M_LINE_END_POINT_SECOND
Retrieves the X- and Y-coordinates of the second intersection point, for the marker occurrence, between the edge's mean line and the box search region. For a stripe marker, the mean line is the mean of the lines following its two edges. If you request a result for a specific edge of a stripe marker, using the combination value M_EDGE_FIRST or M_EDGE_SECOND, M_LINE_END_POINT_SECOND returns the second intersection point of the line following the specified edge and the box search region. If the box search region was rotated using MmeasSetMarker with M_BOX_ANGLE or from an angular search, the intersection will take that rotation into account. For vertical edges, the second intersection point is typically at the bottom of the box search region, while for horizontal edges the second intersection point is typically on the left of the box search region. Note that the intersection point that is considered to be the first (M_LINE_END_POINT_FIRST) or second can change depending on the edge's angle and whether the box search region is rotated.
M_ORIENTATION
Retrieves the orientation of the marker.
| Value | Description |
|---|---|
M_HORIZONTAL | Specifies a horizontal orientation. |
M_VERTICAL | Specifies a vertical orientation. |
M_POLARITY
Retrieves the polarity, for the marker occurrence.
| Value | Description |

M_NEGATIVE | Specifies that the polarity of the edge is negative. |
M_POSITIVE | Specifies that the polarity of the edge is positive. |
M_NEGATIVE | Specifies that the polarity of the second edge is negative. |
M_POSITIVE | Specifies that the polarity of the second edge is positive. |
M_SCORE
Retrieves the score, for the marker occurrence. This score represents how confident you should be that Aurora Imaging Library found what you expected. For a stripe marker, the score is the average of the score of both edges.
M_SCORE_TOTAL
Retrieves the marker's final score. This score represents how confident you should be that Aurora Imaging Library found what you expected. Aurora Imaging Library establishes the marker's final score using all marker occurrences and score characteristics. For a stripe marker, the score is the average of the score of both edges.
M_SPACING
Retrieves the distance between the marker occurrence and the next.
M_STRIPE_WIDTH
Retrieves the width of the stripe, for the marker occurrence. The stripe's width refers to the distance between the position of the maximum edgevalue of the stripe's two outermost edges. This result is only available for stripes.

In this case, you must set SecondResultArrayPtr to M_NULL. For positional results, you can set FirstResultArrayPtror SecondResultArrayPtr to M_NULLif you only want to retrieve the X- or Y-coordinates, respectively. You must always pass at least one pointer.
