I am trying to make OCR recognition of ASCII strings from the image. I am using Tesseract3 library, but I am having a little bit of the problem with correct recognition, so I need to train it with new character set (which is specific). I already discovered this HOW-TO: TrainingTesseract3, but the tutorial has some unnecessary procedures which I do not need, because of the simplicity of my image test set. My image data set comprises only 1 liners, where each of the ASCII characters is the same in all images (no rotation, no scaling), but has variable distance (only horizontal) between characters in the line.
How can I use font images to train the recognition algorithm?
