I’d like to use a camera and some sort of tracking technique to determine if a crowd is leaning to the left or to the right. So if 50 people are all facing the camera with arms in the air - I would like to measure which direction they are leaning.
I think it would work if I was able to capture 3 sample images as templates for comparison: sample 1 would be the crowd standing straight, sample 2 would be leaning left and sample 3 would be leaning right.
I could then compare the current frame with the three templates and determine which was the closest match.
Do you think this is doable in VVVV? Any suggestions as to what nodes/techniques to try would be appreciated.
