How to detect people contours
The guys here detected the contour of people. They say they used OpenCV, but the link to the source code is broken.
I think it could be an intersection of HOG people detection and Canny. Do you have any other idea on how they could make this with OpenCV?
I am afraid that this application is strictly depending on the fact that the background is as static as possible, since they have an approach based on contour analysis. A second person in the room will completely break this system as far as I see. Why not read the paper of their work?
You can do it with the watershed, if you know the mean position of a person in your detector, you can set the marker in the mean position, then it will segment it for you...
Thanks for the comments. It seemed too easy to be truly usable in a real case...
PS: don't have access to ResearchGate, but by a quick look at the abstract I was wondering if it was something to spend my time on. You guys confirmed it's not.
Euhm that I did not say.... researchgate is free if you register. As to the technique itself, first try it then decide whether it is usefull or not. It is always worth spending your time on a paper with the result you desire...
