I wrote a code in MSER algorithm. I got it successful for one image, however, for other one, it reads: 0×0 empty char array. The only change I made was the input image and slight tuning in MSER. How can the OCR fail? Thanks in advance

Hi
I am assuming OCR is not working and you are getting an empty array. Sometimes it require preprocessing to improve the result. You can refer to this documentation for that.
