摘要We propose a pyramid based representation together with a partial weighted similarity measure to address the partial occlusion problem in visual tracking. In current histogram based tracking methods, due to the lost of spatial information, occlusion cannot be handled very well. In this paper, the spatial pyramid based histogram representation is introduced into the Bayesian inference framework, in which approximate global spatial information is retained and multi-scale information is explored. Correspondingly, considering that the visible parts of a occluded target with the high resolution should have more contribution to the similarity judgment, a partial weighted similarity measure is proposed, in which more confidence is assigned to the better matched parts under the finer scale. The Bayesian inference framework i.e. particle filter then leads the sample distributions to propagate over time. Experiments in different challenging sequences show that our algorithm is superior to the state of art histogram based methods, especially when occlusion happens and a little appearance change exists.
