I am working on images with single character. However, tesseract is unable to recognize them.
This is how I initialized it:
tess.Init(NULL, "eng", tesseract::OEM_DEFAULT);
tess.SetPageSegMode(tesseract::PSM_SINGLE_BLOCK_VERT_TEXT);
tess.SetVariable("tessedit_char_whitelist", "ABCDEFGHIJKLMNOPQRSTUVWXYZ");
This is what i do for recognition:
tess.SetImage((uchar*)rotatedImage.data, rotatedImage.cols,
rotatedImage.rows, 1, rotatedImage.cols);
char* out = tess.GetUTF8Text();
I am attaching images
