Webthe corresponding eigenface in the ”sum” of the eigenfaces should be greater. If, con-trary, the particular feature is not (or almost not) present in the original image, then the … Webface which we call an eigenface. Some of these faces are shown in Figure 2. Each face image in the training set can be repre- sented exactly in terms of a linear combination of the eigenfaces. The number of possible eigenfaces is equal to the number of face images in the training set. However the faces can also be approximated us-
Eigenface Approach - an overview ScienceDirect Topics
WebThe algorithm is based on an eigenfaces approach which represents a PCA method in which a small set of significant features are used to describe the variation between face images. Experimental results for different numbers of eigenfaces are shown to verify the viability of the proposed method. Keywords: PCA, Face recognition, Eigenface.

WebSep 13, 2024 · Abstract. In this paper, we propose a PCA-based face recognition system implemented using the concept of neural networks. This system has three stages, viz. pre processing, PCA and face recognition. The first stage, preprocessing performs head orientation and normalization.
