OCRTesseractGetOrientation problems

Post by Slava » Fri Jan 16, 2009 5:29 pm

I have found two difficulties with gdpicture version 5.10.1:

1. OCRTesseractGetOrientation returns wrong rotation on some of ordinary A4 images (professionally scanned invoices). Its a very handy function, but automatically wrong rotated document is very disturbing to user. Can I find the Orientation Confidence somehow? It would be better for my program not to rotate, when not 100% sure.

2. For my Delphi application this procedure negatively affects the OCR done immediately after. For example: After running OCRTesseractGetOrientation ocr does NOT recognize points, commas and other punctuation. For examle 23,95 is recognized as 23J95 or 23t95. Or K.v.k as Ktvilii.

I hope to hear from you soon.

Kind regards,
Slava
