RE: image binarization

Please be careful with the Otsu algorithm, because we use only one threshold value for whole image. No method is best for all cases J. You should do and compare the results between Otsu algorithm and adaptive threshold algorithm. About adaptive threshold algorithm, you can be based on

RE: text rotated upside down or of 90°

Dear Giuseppe, Could you post some samples to analyze? If you are afraid that tesseract page layout doesn't work on rotated image, you can run step-by-step as belows: 1. Firstly, you can call tesseract to FindLinesCreateBlockList (have a look at TessBaseAPI class), you should achieved a

RE: Image pre-processing for good OCR results

Dear Jon, Beginning for analyzing; I try also to detect lines, corners; but results are not good. I think due to images are low contrast. Please try to analyze with some data line profiles: ROI-left-profile: https://picasaweb.google.com/congnguyenba/TesseractBasedOCR#5576706091073985
