摘要：This paper reports an algorithm of traffic multiple targets occlusion processing and tracking based on both the prediction of Kalman filtering operators and the processing of the PCA-SIFT (Principle Component Analysis Scale Invariant Feature Transform) feature with the active operators. The Kalman filtering operators are used for both the prediction of occlusion event and the fast location of occlusion area. The template for each target in the occlusion area is built and the PCA-SIFT feature with the active contour operators is used to estimate and trace the multiple targets separately in the area. Through updating, the occlusion processing and tracking of multiple targets continue until the occlusion ends. Obtained results have shown that the algorithm in the paper can solve multiple targets occlusion and tracking effectively and accurately, comparing with the real trajectories.
