Is there any way to compare these images and detect similarity between them?

See http://www.imagemagick.org/Usage/compare/

It compares two images pixel-by-pixel. If you want a more intelligent comparison, you need to do some image processing first.

Your images are so different that any compare is likely to say they are totally different. One of your images in color and the other is black and white edges. You likely need much more similar images to get anything meaningful out of the compare results.
