摘要：The present invention discloses a system and method for segmentingforeground and background in a video, wherein the system comprises: a video shootingmodule for shooting the video; a data reading module for reading each frame of the

video; a primary segmentation module for establishing a plurality of Gaussian models in afirst color space for each pixel of each frame, and performing a matching processingbetween each pixel of the current frame and the plurality of Gaussian modelscorresponding to the pixel, and primarily segmenting the pixels as foreground andbackground according to the result of the matching processing; and a segmentationrejudging module for performing a rejudging processing to the primarily segmentedforeground and background in a second color space, so as to obtain the finallydetermined foreground and background. The present invention improves the effect offoreground segmentation by using the combination of the color spaces and introducingthe relationship between pixels.
