When scanning and capturing images, we typically want to collect information from the scanned documents. Below are the different recognition technologies that provide that capability:
Optical Character Recognition - provides the ability to recognize text.
Optical Mark Recognition - the ability to read marks or colored shapes.
Intelligent Character Recognition - the ability to read handwritten characters.
Of the three recognition types (OMR, OCR, ICR), Intelligent Character Recognition is the most difficult, and most problematic. It typically takes training on one specific subject's writing to be accurate with handwriting, and to read handpriting, typically it requires characters bound by boxes, or "combed fields".
