Click the OCR/A tab to access the settings that the OCR/A recognition engine uses when it completes recognition on the selected field. Select Square background to read non-dropout checkbox. This setting is stored in the document hierarchy by using the OMRType variable, where 0 is Square background .

Optical Character Recognition (OCR) is the process that converts an image of text into a machine-readable text format. For example, if you scan a form or a receipt, your computer saves the scan as an image file. You cannot use a text editor to edit, search, or count the words in the image file.

Checkbox detection is the task of detecting checkboxes and extracting their status (marked/unmarked) from a given document. Detect Checkbox Marked/Unmarked Status. The next question that comes into our mind is how we could automate the checkbox detection process.

OCR (optical character recognition) is the use of technology to distinguish printed or handwritten text characters inside digital images of physical documents, such as a scanned paper document.

How does optical character recognition work? Optical character recognition (OCR) uses a scanner to process the physical form of a document. Once all pages are copied, OCR software converts the document into a two-color or black-and-white version.

A simple OCR engine works by storing many different font and text image patterns as templates. The OCR software uses pattern-matching algorithms to compare text images, character by character, to its internal database. If the system matches the text word by word, it is called optical word recognition.
