I have been developing an application for License Plate Recognition and I am able to detect the number plate successfully from the image using OpenCV. But the problem is with the output of Tesseract e.g. if there is a number say "BI6 COL" in image, Tesseract detect it as "BISWCDL" I have tried several image preprocessing methods (resampling,morphological operations, binarization...) but the accuracy in results is still low.
Please suggest how can I improve the quality of output
