Abstract

Visual object tracking is an essential task for many computer vision applications. It becomes very challenging when the target appearance changes especially in the presence of occlusion, background clutter, and sudden illumination variations. Methods, that incorporate sparse representation and low-rank assumptions on the target particles have achieved promising results. However, because of the lack of structural constraints, these methods show performance degradation when facing the aforementioned challenges. To alleviate these limitations, we propose a new structural low-rank modeling algorithm for robust object tracking in complex scenarios. In the proposed algorithm, we consider spatial and temporal appearance consistency constraints, among the particles in the low-rank subspace, embedded in four different graphs. The resulting objective function encoding these constraints is novel and it is solved using linearized alternating direction method with adaptive penalty both in batch fashion as well as in online fashion. Our proposed objective function jointly learns the spatial and temporal structure of the target particles in consecutive frames and makes the proposed tracker consistent against many complex tracking scenarios. Results on four challenging datasets demonstrate excellent performance of the proposed algorithm as compared to current state-of-The-Art methods.
