1:	Extract the set ξ of motion vectors from the MPEG stream
2:	Create an empty array ζ to store the motion on X and Y axes
3: 4:	FOR each motion vector V in ξ DO
5:	Get the source and the destination points of the motion vector V
6:	Compute motion magnitude of V
7:	IF magnitude of V > minMontionTh THEN
8:	Compute the x motion corresponding to the X axis and add nCorrection
9:	Store x into ζ on corresponding plane
10:	Compute the y motion corresponding to the Y axis and add nCorrection
11: 12:	Store y into ζ on corresponding plane END
