Motion Detection status

Olivier Singla

I am using the DM368, and want to use Motion Detection. I setup a region Of Interest, but I am not sure if this is working or not... Is there a flag / status I can check to see if a given ROI (0 to 4)  is marked as 'in motion' ?

Thanks.

    Hi,

    Are you using IPNC RDK for DM368? where this features is already supported?

    Can you please give clear details on what are your setting? is it from GUI or from codec interface that you are trying this?

    Regards,

    Raghu

    Hi Raghu,

    I am not using the IPNC RDK. I bought it, but to my big disappointment, it does not contain the source for the implementation )motion detection and other features as well). It uses a library, and the source is not provided. I understand I could use this closed-source library, but this is not the way I want to do things.

    I use then the DVSDK for the DM368. I think the proper way to implement motion detection is to read the motion vectors (as described in http://processors.wiki.ti.com/images/3/39/MV_SAD_usage_info.pdf), and with some interpretation of the MV for the area I am interested in, that should be fairly easy to know which area is in motion.

    Would-you confirm this is way to proceed?

    Thanks!

    Hi Olivier,

    I found the spec at wiki.tiprocessors.com/images/3/39/MV_SAD_usage_info.pdf

    We have worked on motion detection as a GStreamer element.  You can see the technical approach at https://www.ridgerun.com/developer/wiki/index.php/Introduction_to_Motion_Detection#Hardware_accelerated_motion_detection

    I added a section based on the idea of using motion vectors as the input to a motion detection algorithm.  Please share any results and I will add links to your findings.
