查询词典 miss the target

After the human is detected and extracted, we then track body parts of the human by using appearances of these parts as the features and using particle filters as the tracking kernel. In the particle filter, we adopt color histograms as the appearance features and use a specific histogram mapping to enhance the discriminability between different objects. To form a robust tracker that can distinguish target objects from background objects that have color distribution similar to those of target objects, we calculate the target similarity from both the target object model and the background model.
