Target Tracking Using Mean Shift and Dynamic Directional Gradient Vector Flow

In this paper, a new method for contour tracking of mobile target in low quality video sequence is presented. Proposed method helps to track variety of targets exactly while the camera is moving. In this study, a new type of active contour is used with a way for estimating motion model of the target. Estimating motion model of the target uses color and location information together. This information would cause our method not to be sensitive of aspect change. Our method is compared with two other methods: tracking via simple active contour and estimating motion model by using affine transform. Experimental results illustrate our method to outperform the prior ones.
