I am using tesseract to find text in scanned image,
I am trying to set "tessedit_char_whitelist" by calling as follows, so that only alphanumeric search is performed
tes_obj.SetVariable("tessedit_char_whitelist", "abcdefghijklmnopqrstuvwxyz012345789ABCDEFGHIJKLMNOPQRSTUVWXYZ");
When I try to compare results between multiple searches on the same image, I found different results. What might be the reason for different results.
