for training of SVM , you use some image. if you use image with 144*33 pixel your code is fine. but if you use another size , you have this error ! plz check this !

and your error is : sizes of input arguments do not match <the sample="" size="" is="" ........&gt;="" in="" cv="" preparepredictdata,="" <="" p="">

1. we use aspect ratio for detect good region , after that we use SVM.
2. (ans like 1)
3. because we must detect number for OCR
