First, SURF features are extracted from preprocessing images and matched by using the nearest neighbor method.
首先，对经预处理后的序列图像提取SURF特征点，采用最近邻法匹配特征点；
Comparing with the nearest neighbor method, the presented method needs less cost and memory space as the representative samples are only a little part of the training set.
而支撑点仅占全部训练样本的一部分，所以相比最近邻方法具有较小运算量和存储量的优点。
The optimal discriminant features of face are extracted using singular value decomposition and Fourier transform, and then they are classified by the nearest neighbor method. In...
