Temporal differencing.
M(i,j) = F2(i,j) , | F2(i,j)-F1(i,j) | >= Threshold
= 0 , | F2(i,j)-F1(i,j) | < Threshold
where F2 is the current image, F1 is the previous image, and M is the motion image.
First Segment
Segments each motion region using recursive function setlabel( ), and get rid of any region that is too small. (size < prespecified object size) This step gives the approximated sketch of the moving object. We will use this sketch to segment the full object.
