| 摘 要： | 为了提高识别性能,提出运用局部保持投影(LPP)和核直接判别分析(KDDA)相结合的方法进行掌纹识别.在小样本图像识别中,为了解决特征方程矩阵的奇异性,首先运用图像下抽样降低掌纹空间的维数,然后应用LPP提取掌纹局部结构特征作为KDDA的输入提取分类特征,计算特征向量间的余弦距离进行掌纹匹配.运用PolyU掌纹图像库,...

| Abstract: | A palmprint recognition method based on locality preserving projection(LPP) and kernel direct discriminant analysis(KDDA) was proposed in order to improve the recognition performance.In small-size-sample cases(such as image recognition),in order to resolve the singularity of the eigenvalue equation,the image down-sample was first applied to reduce the palmprint space dimension,the LPP was used to extract the local structure features as the input classification extraction features of KDDA,and the cosine dist... |
