See Image.cpp. A different version of compare has metric as a parameter.

-dissimilarity-threshold has no relevance in a simple compare, and it has no effect in your command. It is relevant for subimage search. If you want that, see Image.cpp subImageSearch().

Use a version of compare that gives the double "distortion" value. Then use fprintf or whatever you want.
