A new algorithm under multi-constraints for automatic segmentation of video moving objects is proposed. First, the temporal segmentation separates the initial areas including moving objects accurately from the background by continuous frame difference. Then, the spatial segmentation segments the initial areas into spatially consistent regions by Watershed algorithm based on a color gradient. Finally, regions are classified as foreground/ background by maximizing the a posterior probability
