基于局部保持投影的统计不相关复合信息投影
摘要
为解决在人脸识别领域的特征提取问题
提出了一种基于局部保持投影(Locality Pre-serving Projections
LPP)的统计不相关复合信息投影(UMIP).该方法是基于线性投影的子空间方法
将原始人脸图像看作是一个矩阵
通过相应的代数方法
抽取得到保持原始样本分布信息的低维子空间信息.在UMIST和Yale标准人脸图像库上的实验结果表明
UMIP算法提高了识别率.
Abstract
With the purpose of solving feature extraction problem in face recognition area
a new manifold learning algorithm is proposed
called Uncorrelated Multiple Information Projection(UMIP) based on Locality Preserving Projections.It is an subspace method based on linear projective maps
regards the original picture of face as a matrix
and extracts the lower dimension subspace’s information which optimally preserves the local structure and the global information of the data set by corresponding algebraic method.Th...
