Do you think training one character per file is affecting my results? I was doing it because I have thousands of samples, and makebox always makes too many wrong guesses. If I have all the digits on the same image, fixing the resulting 10k chars box file manually would take forever. On the other hand, fixing a single digit box file only takes a simple regexp replace operation on the resulting box file (one replace for digit 1, another replace for digit 2, and so on).
Also, the goal of my application is for online OCR, to recognize single lines of handwritten digits as the user draws them. Would this affect the format of my sample image(s) as well?
