[0036] Aiming at the problems existing in the prior art, the present invention describes the observation mode of each pixel by combining color information and spatial structure information; and further adopts the framework of mixed Gaussian model, and proposes a mixed Gaussian background model based on joint color information and spatial structure information . The pixel information is represented by the color located in the local area at each position, while the local spatial information is represented by the pixel grayscale feature.
[0037] The implementation method of background subtraction in the present invention mainly includes the following steps: for the current input image, calculate the current observation mode of each pixel by combining local spatial information and color information; compare the current observation mode of each pixel with all modes in the background model, and find The background model mode with the closest distance to the current observation mode...
