OCR Parsing get checkbox or Radiobutton value

Question

I need to parse OCR image file and get all texts and checkbox values, How to get Checkbox or Radio Button value from OCR Parsing and Which one OCR Api is give corrected result extract from image.

Answer 1

Check-box values can be read by specialized OMR software, not OCR. OCR stands for Optical CHARACTER Recognition, and checkmark is not a character, but a compound object consisting of base checkmark object and some kind of mark on top of it. OCR cannot provide a singe ASCII value for such combinaiton to represent a checkmark, thus a special OMR application needs to compare empty and marked value, and generate 1 or 0, true or false Boolean type value. OMR stands for Optical Mark Recognition.
