How Image-compare works
Image-compare is really a nice API sat between the command line and GraphicsMagick. It uses the GraphicsMagick compare method to create a number that represents the difference between the target image and each image in the array. Image-compare then returns the image that has the smallest amount of difference. GraphicsMagick.compare
isn't a silver bullet, you can't get a 100% reliable comparison between images from it. The best way to work out which image from a collection closest resembles another image is to compare the size of difference.
