Abstract:

Based on the rules of speediness and exactness, the method of moving object extraction is proposed only with temporal information. We obtain the frame  difference mask by the intersection of three twice-frame-difference images, then get the moving object mask （MOM） by scanning every column and row. AAt last, by filling MOM with original values we can get the extracted moving object. The experiments show that the method can get a better result with l ess runtime.

Key words: moving object, moving region, frame difference, mask, twice-frame-difference
