Segmentation of non-rigid bodies in affine motion: a new framework

In this paper a new technique for partitioning a non-rigid body (human body), when it is in affine motion is presented. The technique is based on finding the contour in the "modified difference frame". These contours can then be used in identifying the regions of interest. Results show that the technique eliminates a lot of stationary regions and thus can reduce the amount of computational time required for the processing of the image. It reduces significantly the total bit rate required for transmission. It also provides an algorithm for contour tracing using extended boundary concept and contour compression by contour merging.
