- Application of kfda in evaluation system of neckline performance
在领口质量评价系统中的应用 - In training process , we use kernel - based fisher discrimination analysis ( kfda ) method to train the input sample vectors . the method has been used in face recognition and has been demonstrated better recognition capability than other methods ( pca , kpca , svm ) . we calculate the optimal subspace wopt and project the sample gait sequences to wopt , then get the tracks of the sequences , calculate the track centroid and calculate the exemplar projection centroid of the sequences in the same class , and the exemplar projection centroid represents the class template . to test the class of a gait sequence , we also project the test sequence to the eigenspace , and calculate the track centroid , then calculate the euclidean distance of the test sequence tracking centroid with the sample sequences ’ exemplar projection centroids . and the class which the test sequence belongs to is the one that the sample sequence which the euclidean distance is shortest belongs to
该方法在人脸识别的研究中已有采用并在同样测试条件下取得比其他识别方法更好的识别性能。采用kfda方法取得最优特征空间wopt ,把步态样本序列映射到wopt中,取得样本序列在特征空间中的轨迹,计算轨迹质心,把同类样本序列的轨迹质心进行平均求得该类的标本投影轨迹质心,作为该类的模板。在识别时,将测试序列也投影到特征空间中,取得序列轨迹质心,对测试序列轨迹质心与样本的标本投影轨迹质心计算它们的欧氏距离。
