Latest Patents
Quang H Nguyen holds a patent for a "System for background subtraction with 3D camera." This system includes a computing device connected to a 3D video camera. The processor of the device is programmed to receive a video feed containing images of one or more subjects, which include depth information. The processor segments pixels and corresponding depth information into three different regions: foreground (FG), background (BG), and unclear (UC). It categorizes UC pixels as FG or BG using a function that considers the color and background history (BGH) information associated with the UC pixels and the color and BGH information associated with nearby pixels. The system examines the pixels marked as FG and applies temporal and spatial filters to smooth the boundaries of the FG regions. It constructs a new image by overlaying the FG regions on top of a new background and displays a video feed of the new image on a display device while continually maintaining the BGH.
