This paper presents a full system for vehicle detection and tracking in non-stationary settings based on computer vision. The method proposed for vehicle detection exploits the geometrical relations between the elements in the scene so that moving objects (i.e., vehicles) can be detected by analyzing motion parallax. Namely, the homography of the road plane between successive images is computed. Most...
Rao-BlackWellized particle filters have achieved a breakthrough in the scalability of filters used for Structure from Motion (SFM) and Simultaneous Localization And Mapping (SLAM). The new generations of these filters employ as proposal distribution the optimal i.e, the one taking into consideration not only the previous motion of the camera, but also the most recent measurement. However the way they...
In this paper, we propose a method of digital zooming by automatically recognizing the soccer game events such as penalty kick and free kick based on player and ball tracking. We also propose an efficient and stable ball tracking method by switching search methods between global search and local search. In the frames where the ball is lost as well as in the first frame, the global search with normalized...
