Abstract :
A moving object segmentation algorithm in the wavelet domain is proposed. The change detection method with different thresholds in four wavelet sub-bands is used. After merging the different edge masks of four sub-bands with the inverse wavelet or the union operation, further object shape information and more accurate extraction of the moving object is obtained.
