Stabilized frames, KLT Sparse flow and EM results
Using motion statistics from KLT sparse flow on dense optical flow : Column 1: stabilized frame (top) and current frame (bottom).
Column 2: KLT sparse flow on stabilized frame (top) and motion mask obtained by thresholding the magnitude of the robust flow by KLT motion statistics (bottom).
Column 3: horizontal and vertical components of optical flow btw stabilized frame and current frame.
Column 4: mixture clusters on sparse flow obtained via EM.
