Summary:
Up to now, the majority of the background modelling methods are pixel-based and rely heavily on hardware optimizations to process standard definition videos in real-time. There are far too complex and require too much resources (time, memory, etc.) to be applied to Ultra High Definition (UHD) videos. We propose a fast background modelling method which divides the complexity through time via the update of multiple small blocks. By using mix of linear and random selecting order we insure that all blocks get updated in a known number of frames. Preliminary results show that we can reduce by at 80 times the modelling time compared to a full frame modelling and reach an average processing speed of 77 fps for 4K videos.
