Image recognition


#1

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
