SYSTEM FOR BACKGROUND SUBTRACTION WITH 3D CAMERA

摘要

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

主权项

1. A system for background image subtraction comprising:
at least one processor and memory, the at least one processor programmed with one or more instructions, which when executed cause the at least one processor to: receive a video feed, the video feed comprising at least one colored image of at least one subject, and depth information; categorize pixels of the at least one colored image as foreground (FG), background (BG), or unclear (UC); re-categorize UC pixels as FG or BG using color and background history (BGH) information associated with the IX pixels and color and BGH information associated with pixels near the UC pixels; and construct a new image using the FG regions and a new background.
