![]() This tells engine to search for relatively possible characters in and outside the dictionary in the defined area where the precision to identify is low. Low: This is the Low Confidence factor which user can opt when they are less sure that the character can be recognized by an OCR engine, so they set this.This tells engine to search look for the possible characters in the defined area. Medium: This is the medium Confidence factor which user can opt when they think the character may or may not be recognized by an OCR engine, so they set this.High: This is the highest Confidence factor or precision which user are sure that the character is large and visible enough (not hazy or compacted) to be recognized by an OCR engine.So, the right setting is a balance between finding all the right characters and not include too much that ruins the result, and will depends on the font, colors, background, size of the text. ![]() Setting a lower precision means that in general more characters are found, but the assurance that it’s the right characters is lower than with a high precision. On the other side a high precision can result in that some characters are not found. With a high precision you can be very confident that the characters found are the correct characters. This means, a higher OCR precision level requires a higher confidence in the OCR engine before a certain character is matched. OCR precision sets the accuracy of the OCR results on a character level.
