Histogram-based particle filters have emerged as an appealing method for the target tracking. As colour and shape features are widely used to represent the target, we propose in this paper a novel method to combine these two features by assigning an adaptive weighting factor to each feature, in a particle filtering framework. In other words, the feature with higher likelihood and the property of high...
In this paper, we address the problem of segmentation-based tracking of multiple articulated persons. We propose two improvements to current level-set tracking formulations. The first is a localized appearance model that uses additional level-sets in order to enforce a hierarchical subdivision of the object shape into multiple connected regions with distinct appearance models. The second is a novel...
