i have videos which captured human movement in bird eye view. need to trace the same and analysis the movement pattern. pls suggest me a free software available for research.
As far as I know several professional softwares (like premier) have tracking features. Otherwise, a very good solution is kinovea. Kinovea is a video player for sport analysis. It provides a set of tools to capture, slow down, study, compare, annotate and measure technical performances. And, most importantly, is free and open source.
