Multifeature object tracking using a model-free approach

In this paper we introduce a new model-free method for object tracking. The tracking is posed as a segmentation problem which we solve using the watershed algorithm. A framework is defined to compute the required topographic surface from distances to the predicted contour intensity, edges and motion edges. This multifeature tracking approach yields accurate results in the presence of object corners, image clutter and camera motion. Results on real sequences confirm the stability and robustness of the method. Objects are tracked over long sequences and in the presence of fast object motion
