This is looking really good. I modified your code below so I could run some tests. What it does is run a loop that first records the actual cell levels for the original scene. It then does a standard wait for motion to happen. Once motion is detected, it checks the current cell levels until they are the same as the original scene. This test doesn't trigger the camera but only displays a message.
Function fill_md_array(name) records the scene levels and function compare_scenes(original, current, sensitivity) does the scene comparison. The sensitivity value allows for the fact that the levels will probably never match exactly.
This works fine on my desk - now for a real life test.
