Hello everyone. I just started using Tesseract-OCR 3.02 to recognise numbers only.
The number themselves are *probably* in Futura Bold font, styled in a particular manner (see images). Using the "digits" parameter, Tesseract-OCR would either get it perfectly or fail completely (return a blank). After quite a bit of testing, it appears that it is the "crop" of the image is what makes or break. For instance: <https://lh3.googleusercontent.com/-I6vx1-5KxGY/VepwFvh_OmI/AAAAAAAAABw/kSXSI8qsJiU/s1600/Test1.png> When poorly cropped as above, with quite a bit of horizontal and vertical blank, the engine will always fail to return anything <https://lh3.googleusercontent.com/-8IMD05QoIYY/VepweKPrTxI/AAAAAAAAAB4/EFfQGgoD4CM/s1600/Test2.png> A crop like this, with a some space for extra digits would fail in this particular example, but succeed at time. <https://lh3.googleusercontent.com/--fH0jI8pEeQ/VepyLQAw6zI/AAAAAAAAACE/Qm22VlnbqGI/s1600/Test3.png> A crop like this, has so far always worked. The problem is that I am capturing the image automatically and need to cover for a range of at least 5-7 digits. I would never need to crop as badly as the first example, but I do need more leeway than the last one allow. Is there anything I could try to make something like the middle crop work better?
