OMR vs. OCR: Know the Difference
By Shumaila Saeed || Published on February 11, 2024
OMR (Optical Mark Recognition) interprets human-made marks on documents, while OCR (Optical Character Recognition) digitizes and interprets printed or handwritten text from images.
Key Differences
OMR, or Optical Mark Recognition, is a process primarily used to detect marks made on predetermined positions on documents. OCR, or Optical Character Recognition, involves recognizing and interpreting alphanumeric characters in a digital image.
