Frame differencing

[mm2ps]

Do you think that it is possible to carry out some sort of frame differencing with the AVRcam?

Thanks,

Hmm...yeah, I think it would be possible to add some sort of frame differencing. Typically, this is done by segmenting each frame into a matrix, and then looking for changes in quadrant of the matrix. Imagine a checkerboard where each square is somehow being evaluated to determine if it is similar or different from the previous.

It would be some work, but probably doable. Especially if you don't need to do the full framerate of the camera.

So, is there memory to keep a reference/previous/averaged frame upon which the differencing of the incoming frame can be done?

And, full frame rate is not required.
