Can we apply OCR to the output image for text recognition?

The code doesn’t with other images.. only with the test image. Also, the final image wasted grayscaled; but that can be adjusted. Although this doesn’t work with every image.

you need to download opencv, numpy and mapper by python's pip package manager. goto the folder of the project -> open command line on that location -> type "pip install opencv-python" also do "pip install numpy" and for mapper also download the mapper.py file from github
