I am trying to scan a business card using tesseract OCR, all I am doing is sending the image in with no per-prossesing, heres the code I am using.
Tesseract* tesseract = [[Tesseract alloc] initWithLanguage:@"eng+ita"]; tesseract.delegate = self; [tesseract setVariableValue:@"0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ@.-()" forKey:@"tessedit_char_whitelist"]; [tesseract setImage:[UIImage imageNamed:@"card.jpg"]]; //image to check [tesseract recognize]; NSLog(@"Here is the text %@", [tesseract recognizedText]); Picture of card <http://imgur.com/nQPG6iq> This is the output <http://imgur.com/poikzBn> As you can see the accuracy is not 100%, which is not what I am concerned about I figure I can fix that with some simple per-processing. However if you notice it mixes the two text blocks at the bottom, which splits up the address, and possibly other information on other cards. How can I possibly use Leptonica(or something else) to group the text somehow? Possibly send regions of text on the image individually to tesseract to scan? I've been stuck on this problem for a while any possible solutions are welcome! -- -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
