In our framework, color model and shape model are adaptively fused, a new model update scheme is also proposed, this improves the stability of the object tracking. 同时，在新的跟踪算法框架中，将颜色模型和形状模型自适应的融合，并采用一种新的模型更新方法，这提高了目标跟踪的稳定性。
One of the key challenges in deformable shape modeling is to estimate a meaningful average or mean shape from a set of unlabeled shapes. 摘要可形变形状模型化的一个关键问题就是从一系列未标记的形状点集中估计一个有意义的平均形状。
