Basic concepts for the Aurora Imaging Library OCR module

The basic concepts and vocabulary conventions for the Aurora Imaging Library OCR module are:

Acceptance level. The user-defined level against which the match score is compared to determine if the match is valid.
Character representations. The grayscale bitmap (image) or ASCII representation (drawing) of a character used by Aurora Imaging Library OCR.
Entire text. One or many strings contained within the target image.
Fixed size font. A series of character representations that have same character Y size and character X size. Characters of a fixed size font tend to be all upper-case. [Image: dimen.png]
Match score. The result of a read/verify operation that shows the level of correlation between the character representations in the OCR font and the characters found within the image, taking into account character constraints.
OCR font. The Aurora Imaging Library OCR font contains the character representations.
OCR font context. An Aurora Imaging Library object that stores the OCR font information, target image character size and spacing, constraints, and processing controls.
Target string(s). The text to be found within the target image. This can be as little as a single character or multiple lines of characters.
