Abstract (en)
[origin: FR2776459A1] Procedure works by calculation of the difference in values of corresponding pixels in successive images or frames. The resulting difference signal is quantified into n-ary signals with n odd, (N-1)/2 quantification levels for positive differences and (n-1)/2 negative levels and one level for those difference values exactly zero. Region growth and breaking down steps are executed
