摘要:
提出了一种将局部特征加权与二维主成分分析相结合的局部加权的二维主成分分析方法.引入了二维局部加权特征子空间的概念，将各类样本映射到这个局部加权特征子空间，再通过计算测试样本到加权子空间的距离进行样本的分类.使用这种方法在ORL人脸库上进行测试，结果表明，经过局部特征加权的二维主成分分析方法比普通的二维主成分分析方法具有更优的性能，并且在提高识别率的同时算法的复杂程度并没有明显增加.
Abstract:
This paper proposes face recognition software that uses twodimensional principal component analysis (2DPCA) in conjunction with partial feature weighting by applying twodimensional partialweighting to the characteristic subspace. First faces are mapped onto this partially weighted 2DPCA subspace, then the samples are classified by calculating the distance from the samples to the partially weighted 2DPCA subspace. To test this new method, ORL face databases were used and it was found that the recognition rate was higher than with either 2DPCA or PCA and the computational complexity did not increase significantly.
