基于（2D）2NMF及其改进算法的人脸识别
人脸识别 非负矩阵分解 二维非负矩阵分解
2009/2/11
非负矩阵分解(NMF)是基于部分的特征提取方法，能够克服局部遮挡和光照问题，在图像识别任务中效果较好。然而传统算法中，NMF提取的特征是非正交的，且二维图像常被向量化处理，不仅丢失一些结构信息，还导致了数据的高维，不利于提高识别精度和速度。利用图像矩阵取代传统的图像向量表示，提出新的(2D)2NMF方法提取二维图像特征，并通过特征正交化和图像变形等措施，改善了算法性能。人脸识别实验表明，上述措施能...

2008/12/29
提出了一种联合图像二维离散小波变换（2D-DWT）和二维主成分分析（2D-PCA）的人脸识别方法。首先通过2D-DWT将当前图像分解成四个子图像，其中一子图像对应原图像的主体部分（低通部分），其余三个子图像则对应图像的细节部分（高通部分）。在此基础上，采用2D-PCA方法分别对每一子图像进行特征提取。此外，文中还提出了一种简单有效的方法对各子图像中所提取的特征进行融合，根据所得到的特征进行人脸识别...
