I'm struggling with the OSD function of Tesseract 3.02. I tried the standalone version via command line and the Tess4J version too, but I always obtain an error with different input types.
I downloaded the osd.traineddata for version 3.01 (I guess no such file still exist for v3.02) from here https://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-3.01.osd.tar.gz&can=2&q= and I copied it properly in the TESSDATA folder Below my experiments: COMMAND LINE tesseract input_image output_text -l eng -psm 0 response: Error during processing. With psm = 1 it read text with very bad quality, with psm = 2 or 3 it give my empty output. As far as I know only 0 and 1 values perform OSD! From the reference: 0 = Orientation and script detection (OSD) only. 1 = Automatic page segmentation with OSD. TESS4J Tesseract instance = Tesseract.getInstance(); instance.setLanguage("ita"); instance.setPageSegMode(TessPageSegMode.PSM_AUTO_OSD); String result = instance.doOCR(myImage); result always is empty at the end To know the input orientation it's critical for my project but at now I'm not able to find a way to accomplish this. I hope somebody can help me! Thanks in advance -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
