A new background reconstruction and moving foreground extraction algorithm is proposed for stereo video with static backgrounds. Firstly
based on the left and right foreground of moving region by using Frame-Difference method
the enclosing rectangles of the moving foreground areas are initialized
and the background is reconstructed based on the initial block. Then
the left and right moving foregrounds are separated by comparing the reconstruction of the backgrounds information with every frame images. The result of the experiments shows that it can achieve the segmentation accurately and reduce the stereo matching time and the information storage significantly.
