Hi there!

Is there any possibility to preserve the document colors in the final result? @andrewdcampbell

Kind Regards, João

Some of my notes are containing colors important to their content. My local version has a flag for disabling w/b conversion. You can replicate that by:

commenting out this range https://github.com/andrewdcampbell/OpenCV-Document-Scanner/blob/master/scan.py#L291-L298
updating the variable thresh to warped in https://github.com/andrewdcampbell/OpenCV-Document-Scanner/blob/master/scan.py#L302

Cheers
