Dynamic Illumination Compensation For Background Subtraction

摘要

A method of processing a video sequence in a computer vision system is provided that includes receiving a frame of the video sequence, computing a gain compensation factor for a tile in the frame as an average of differences between background pixels in the tile and corresponding pixels in a background model, computing a first difference between a pixel in the tile and a sum of a corresponding pixel in the background model and the gain compensation factor, and setting a location in a foreground mask corresponding to the pixel based on the first difference.
