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.

当人体被侦测及切割出来后，接著我们使用人体部位外观当作特徵并且使用粒子滤波器作为核心来追踪此人体，我们采等化之颜色统计表当作粒子滤波器中使用的外观特徵以强化不同物体的鉴别率，为了建立可稳健区别目标物及背景物体的追踪器，我们同时使用目标的模型和背景模型来计算目标物的相似度，为了对抗背景及目标物的外观变化，背景模型及目标物模型都是可适应变化的。
