提取了一种手势识别的算法，通过皮肤颜色模型将手势分割出来，然后追踪其边缘，再通过傅里叶系统作为特征向量进行识别。识别率很高的。(A gesture recognition algorithm is extracted from the skin color model, then the gestures are segmented, then the edges are traced, and then the Fourier system is used as the feature vector to identify. The rate of recognition is very high.)
