The functions prefixed with Mmeas make up the Measurement module. The Measurement module allows you to find markers (for example, edges) in an image, based on differences in pixel intensities. Upon finding a marker, the module returns the marker's spatial reference position and measures features such as its width and angle. You can calculate measurements between two markers, such as the equation of the line that joins them. You can also use the Measurement module to specify explicit points, which you can use as a reference position. The Measurement module can operate on 8-bit or 16-bit unsigned grayscale images. Measurements are made and results are returned with subpixel accuracy.
