Abstract: It is a hard job to track the moving objects in video sequence.Considering disadvantages of watershed transform,a novel moving object tracking algorithm was proposed based on Hausdorff distance.In the algorithm,firstly Canny edge detector was adopted for the image boundary generation,and multi-scale watershed transform was used to initialize contour of the objects.Then the matching of the objects was judged by partial Hausdorff distance.Finally,multi-scale watershed transform was reused to update the object model.Experiment results show that the proposed algorithm can efficiently track more than one non-rigid moving object simultaneously.
