detect try 3.py deals with multiple people, not suitable to large amounts of noise

detect try 4.py deals with at most 1 person, suitable to large amounts of noise (using extra restrictions e.g. distance travelled per frame)

Implementation

subtract background, threshold to BW image

detect significant countours, identify centroids

track between frames: minimum sum of distances between prev and new centroids

(NOTE: standard object trackers don't work well)
