I have a picture that consists of 4 people. My goal is to extract the four people based on the edge detection only. Is it possible? If yes how do I make the approach?
Threshold to find the people, then use watershed. See this for an example: http://blogs.mathworks.com/steve/2006/06/02/cell-segmentation/
Please after applying canny, and getting the edge, please how can I extract only the edge I get to aquire the pixels of edge only without background, and get the gray value of the pixels of edge only, without background.
