Can tesseract read handwriting?
In the current work, Tesseract 2.01 is used for developing user-specific handwriting recognition models, viz., the language sets, for the iJIT system. To generate the language sets for each user, Tesseract is trained with labeled handwritten data samples of isolated and free-flow texts of lower case Roman script.
Does OCR use GPU or CPU?
OCR is a CPU HOG. It will take 99% of any single thread when it is running, so putting energy into a more powerful CPU with more threads is not a bad idea.
