image processing issue #139

Closed NoobCoder-f closed 3 years ago

NoobCoder-f commented 3 years ago

I am facing a small issue when I applying image black and white it is converting a color image to too match black and white so I want to change the image contrast, brightness, and thresholding. I need to apply Adaptive Gaussian Thresholding.

You might have to modify the current implementation of getBWBitmap in scan.cpp and do an NDK build.
