Hierarchical threshold technique oriented to video object segmentation

This paper proposed a motion vector error function to segment the objects in video sequence. The key point of the segmentation technique is how to set the appropriate threshold to distinguish the global motion region from the local motion region precisely. This paper also proposed a hierarchical threshold technique based on global motion estimation to solve this problem. Experimental results show that the proposed techniques are robust techniques which refine the set of global motion pixels hierarchically and segment the video objects effectively.
