Tracking Moving Objects Using an Active Contour Model Based on a Frame Difference Map

차 영상 맵 기반의 능동 윤곽선 모델을 이용한 이동 물체 추적

This paper proposes a video tracking method for a deformable moving object using an active contour model. In order to decide the convergent directions of the contour points automatically, a new energy function based on a frame difference map and an updating rules of the frame difference map are presented. Experimental results on a set of synthetic and real image sequences showed that the proposed method can fully track a speedy deformable object while extracting the boundary of the object exactly in every frame.
