I implemented a sub image detecting system using the compare command of imagemagick.
command = "compare -metric MAE -subimage-search "+image1+" "+image2+" null: ";
I used the above command in subimage detection. But it gives fine results only for some images. Some times it's detecting wrong images as the sub images of the original image. Can you tell me way to avoid this problem?

Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.. You can post images to any free hosting service and put the URLs here.

Please note that subimage detection using compare is sensitive to rotation and scale. So if your images are too different in scale and rotation, it will not work well
