Face Recognition Using Pca Principal Component Analysis By Sahana In this paper, we propose a novel approach to face recognition based on modular pca (principal component analysis). the proposed method improves the accuracy and efficiency of face. Eigenfaces, proposed by sirovich and kirby in 1987, use principal component analysis (pca) to extract the most important features from a set of face images. the extracted features, or eigenfaces, are then used to represent and recognize new faces.
Ppt Face Recognition And Detection Using Principal Component Analysis In this paper, we proposed a face recognition system with local binary pattern with dct using doubly truncated multivariate gaussian mixture model. by using em algorithm with k means or hierarchical clustering, the model parameters are estimated. This scheme build a simple and complete face recognition system using principal component analysis (pca). this method applies linear projection to the original image space to achieve dimensionality reduction. In this paper, an improved principal component analysis (ipca) is presented for face feature representation. ipca is mainly designed to extract the useful information from original face images through reducing the dimension of feature vectors. Techniques for recognition. our approach treats face recognition as a two dimensional recognition problem. in this scheme face recognition is done by principal component analysis (pca). face images are projected onto a face space that encodes best variation among known face images. the face space is de ned.

Extensive experiments on the orl and feret face database are reported to illustrate the performance of the patch based pca. our method promotes the accuracy compared to one dimensional pca, two dimensional pca, and two directional two dimensional pca. 1. introduction. In this paper, we first give an overview of face recognition, and propose the concept of face recognition, the content of face recognition, including face detection, feature extraction and face recognition. In this paper, we propose a novel approach to face recognition based on modular pca (principal component analysis). the proposed method improves the accuracy and efficiency of face recognition by dividing the face image into multiple overlapping sub blocks, and then applying pca to each sub block independently. Principal component analysis (pca) involves a mathematical procedure that transforms a number of possibly correlated variables into a smaller number of uncorrelated variables called principal components.
