Hello! I have a question about the -PSM 0 option with Tesseract. I have 3.01 running in both Windows and Ubuntu Linux and both are successfully OCR'ing images to output files. I am attempting to use the Orientation and script detection (OSD) only option (-PSM 0) but my output text files are always blank. After doing a lot of searching on this forum and the net in general, it seems that many people are observing similar behavior. Here are some questions that I have regarding it's usage:
1. Does anyone know what this option is supposed to do? 2. Is it used to detect page orientation, or am I misunderstanding it's use and attempting to make it do something that it wasn't built for? 3. If it is for page orientation detection, how do I get it to output some sort of value to let me know if Tesseract has determined what the page orientation is? I know that something is working with OSD due to the fact that when I use - PSM 1 on an image that has been rotated 180 degrees, the engine successfully detects the rotation and the output text is correct after processing. Any help would be greatly appreciated! gb -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
