Tesseract character recognition and C++

[Fish Money]

I read single characters with C++ and tesseract/leptonica. Below is chunk I use.

is it possible to improve accuracy to use some special function, in case if I read only one character. Of course I have openCV mat with cropped image to fit the character size.

char *outText1;

tesseract::TessBaseAPI *api1 = new tesseract::TessBaseAPI(); if (api1->Init(NULL, "eng")) { fprintf(stderr, "Could not initialize tesseract.\n"); exit(1); } api1->SetImage((uchar*)imgWarpCopy1.data, imgWarpCopy1.size().width, imgWarpCopy1.size().height, imgWarpCopy1.channels(), imgWarpCopy1.step1()); outText1 = api1->GetUTF8Text(); int temp1 = strlen(outText1); string_read = outText1[temp1-3]; api1->End(); delete api1; delete [] outText1;

If there would be a magic function for improving accuracy that works for any case we would implement it years ago.

Please read relevant documentation where we collected tesseract best experiences.

Image preprocessing depends on the image you did not show (instead of that you posted not formatted code) - please think before sending a post to (any) forum.
