  • http://docs.opencv.org/2.4/modules/core/doc/operations_on_arrays.html#absdiff and threshold afterwards, then mask the image. – Micka May 14 '17 at 21:00

Since you're using Marvin, take a look at the MergePhotos plug-in. This plug-in need to construct the background model to merge the photos.

It was already discussed on Stack Overflow:
how to merge Images and impose on each other

The plug-in source code demonstrates how to use another plug-in: DetermineSceneBackground. This last plug-in can be used to construct the background model or you can check the source code and use it to develop your own approach.
