Sheraz,
I think that it's better to think about the processing that you are trying to achieve. The 3-D
signal is a color signal, so a better question would be: how do I detect edges in a color input?
That problem can be solved in different ways. One, simple approach is to convert color image to
grayscale and then run the edge detection. The edge detection block in the Video Blockset is
designed to handle single color plane and does not operate directly on color input. You can
run your 3-D input (color video) through a conversion to grayscale or you can operate on separate
color planes and then combine the results into a single output, etc.
