In this work, we propose a robust and flexible appearance model based on the structured sparse representation framework. In our method, we model the complex nonlinear appearance manifold and the occlusion as a sparse linear combination of structured union of subspaces in a basis library, which consists of multiple incremental learned target subspaces and a partitioned occlusion template set. In order...
Tracking humans in video is a challenge because of data association and mutual occlusion problems. This paper presents a Gaussian mixture probability hypothesis density-based visual tracking system with game-theoretical occlusion handling. First, a two-step occlusion reasoning algorithm is proposed to determine the occlusion region. Then, an improved spatial color appearance with interferences by...
