Image classification. Image detection is cartoony

I have a large number of JPEG thumbnail images ranging in size from 120x90 to 320x240, and I would like to classify them in both Real Life and cartoon style.

How to do using ImageMagick utilities: convert, compare, identify? Or are there other programs that will do the trick?

opencv (which deals with computer vision) may be more useful for some idea of ​​how the “image classifier” is trained with training data.
