Hi All,
     I am intended  to design motion detection module in verilog. For that I am using use edge information of image . I have already prepared a module for edge detection using Sobel operator. So I can say I am getting edge image in the output. This edge image contains horizontal and vertical edge pixels in the output.
    How can I use this output in motion detection? What further steps are needed to detect motion? Any suggestion or reference from your side will be useful.


Thanks,
Ashish Devre
