Thanks for your answer first; I use tesseract in C#, a client program for a windows.this program use camera to get picture from OLED Led Screen and send to preprocess and then Call the the tesseract's api of c# version (which encapsulates the tesseract of c++ version) to recognized . So the original image seems that is more diffcult to preprocess.I have tried some ways like Gaussian Blur. Maybe the preprocessing method I use is not good enough , i can't get a satisfactory result. the orginal pictures: [image: camera.jpg]
