Motion-Based Moving Object Tracking Using an Active Contour

It is quite important to decide the local converging direction of an active contour for correctly extracting the boundary of a moving object with a deformable shape.

Summary:It is quite important to decide the local converging direction of an active contour for correctly extracting the boundary of a moving object with a deformable shape. Thus, a new energy function for the active contour is proposed based on the addition of a directional energy term using a frame difference map to the greedy snake. The frame difference map is used to obtain the motion information of an object with a faster and non-rigid motion. Plus, updating rules for the frame difference map are also developed to encourage a stable convergence of the contour points. Experimental results on real image sequences showed that the proposed method could fully track a speedy deformable object while exactly extracting the boundary of the object in every frame
