Simple class to read a capture, play/pause/backward some frames This class can be used as main template for other programs

TODO Read a file, detect background, split in video extracts containing movements

Given a "reference" polygon, stabilize image by forcing polygon coordinates

Some test in diffing two images to extract movement and polygons in them

shape detection in a single image

Same tests, with first frame as reference polygon detection, "follower" algorithm to detect trajectory of polygons TODO : retry with another bg subtractor and better "main loop"

First tests with BackgroundSubtractorMOG method to extract background Seems to be CPU consuming

Another try : detect crossing thru 2 reference lines May works fine if people don't collide, but still need work on way to deduce movement direction from various cases

• Gate : class to handle "2 lines" concept in lineFilter

class to keep track of several steps in a program

Body detection, from http://www.pyimagesearch.com/2015/11/09/pedestrian-detection-opencv Works fine only in front view

old test to detect and track polygons

test code on storing data with ttl
