System for background subtraction with 3D camera

摘要: A system for background image subtraction includes a computing device coupled with 3D video camera, processor of the programmed to receive feed from camera containing images one or more subject that include depth information. The processor, an image: segments pixels and corresponding information into three different regions including foreground (FG), (BG), unclear (UC); categorizes UC as FG BG using function considers color history (BGH) associated BGH near pixels; examines marked applies temporal spatial filters smooth boundaries regions; constructs new by overlaying on top background; displays in display device; continually maintains BGH.
