Abstract: Gesture analysis is an important region in Human Computer Interaction（HCI） technology，hand tracking is a key step of gesture analysis.In this paper，algorithm with skin color model and dynamic tracking window is proposed.It uses skin color detecting in image sequences to get binary images and then approaches hand region by using dynamic tracking window.Experimental results show that the algorithm is effective，and also meets the requirements of real-time.

摘要： 手势分析是HCI（Human Computer Interaction）技术的重要研究领域，而手势跟踪是手势分析的的一项重要步骤。提出了一种结合肤色模型和动态跟踪窗口的手势跟踪算法。算法首先在序列图像中进行肤色检测将图像二值化，然后用动态跟踪窗口逼近手部区域。实验结果表明，该算法是有效的，同时也能满足实时性的要求。
