Video Motion Detection using DM648

Hello There:

Has anyone had any experience in the implementation of detecting motion through video?

I would appreciate any help.

Thanks;

Gabriel

    I have seen this sort of thing at presentations before, there was a TIDC presentation for video analytics that may be interesting to you, though it goes above and beyond mere detection of the motion, you should be able to take a look at the presentation in the TIDC archives.

    Interesting presentation.  On page 32 they talk about doing double buffered dma to speed up processing, then on page 34 they state that the edma is not a good option.  Did I miss something?  I am assuming that they mean edma without ping-pong buffers is not a good idea, please correct me if I'm wrong.

    I believe your assertion is correct, it sounds like they mean to just use the EDMA and wait on it being bad instead of having a ping pong type setup whereby the EDMA can continually transfer while the CPU is working in parallel. I think this ping pong buffering is what they are calling scratch and they are comparing using the DMA itself to using DMA in a scratch context.

    Unfortunately this is a presentation I did not get to catch at TIDC so I am just interpreting it like you :).
