The attached project illustrates how to obtain the confidence values for each character and word recognized by our OCR. You must first OCR the image, then obtain a list of each character recognized using L_DocGetRecognizedCharacters. This function creates an array of the structure RECOGCHARS. This structure contains a field nConfidence, which, when bitwise operations are performed to the field you obtain the confidence for each character and word. Below are the bitwise operations:
Word Confidence: nConfidence >> 7 // if equals 0 certain of word otherwise uncertain
Character Confidence: nConfidence & 127 // if < 64 OCR is confident of character.
