In this paper, an integrated video surveillance system for robust tracking is introduced. In the blob detection part, an optical flow algorithm for crowded environment is studied experimentally and a comparison study with respect to traditional subtraction approach is carried out. In the segmentation part, different algorithms are fused to develop a hybrid algorithm for stable segmentation, and validation...
Enormous accessible broadcast soccer videos demand an efficient ball and player trajectory extraction framework to represent the tactic semantics for the automatic analysis. Camera motions, noise and blurs in broadcast videos make it difficult to extract the trajectories with a single existing object tracking algorithm. In this paper, we propose a novel framework for ball and player trajectory extraction...
This paper proposes a real-time object segmentation method based on SOFM network for MPEG compressed video. First, we introduce the macro-block structure of the MPEG encoded video and the preprocession of motion vectors, then the motion vectors are given as input to the self-organizing feature maps (SOFM) models which can automatically estimate the number of objects of the motion model, and the motion...
