Hello,

I need to write a software who read an image from a questionary, and
recognize the options marked.
Anyone knows any gem who has some function like it? I'm think about use
rmagick.

Thanks,

Michel

My idea of a workflow would be as following:
- load the image
- crop to each question
- convert that extract to black/white
- create a histogramm
- count the number of black pixels.

Could be all done with RMagick
