Abstract. In this paper, we define the notion of C*-affine maps in the unital *-rings and we investigate the C*-extreme points of the graph and epigraph of such maps. We show that for a C*-convex map f on a unital *-ring R satisfying the positive square root axiom with an additional condition, the graph of f is a C*-face of the epigraph of f. Moreover, we prove som...

Face hallucination is a task of generating high-resolution (HR) face images from low-resolution (LR) inputs, which subfield the general image super-resolution. However, most previous methods only consider visual effect, ignoring how to maintain identity face. In this work, we propose novel model, called C-Face network, can generate HR with high quality while preserving information. A recognitio...

The current research paper is an implementation of Eigen Faces and Karhunen-Loeve Algorithm for face recognition. The designed program works in a manner where a unique identification number is given to each face under trial. These faces are kept in a database from where any particular face can be matched and found out of the available test faces. The Karhunen –Loeve Algorithm has been implement...

This thesis describes a representation for objects and scenes that is stable against variations in image intensity caused by illumination changes and tolerant to image degradations such as sensor noise. The representation, called a ratio-template, uses low-resolution ordinal contrast relationships as its matching primitives. The choice of these primitives was inspired not only by considerations...

In this study we will able to find an introduction to the work done by other researchers related to the problem of face detection will be presented. It gives a good insight into the problem and overviews the different algorithms used in attempt to solve the problem. In this paper we study 6 most popular face detection algorithms. These algorithms are Face detection using Eigen Faces, Hausdorff ...

We tried to develop a real time face detection and recognition system which uses an "appearance-based" approach. For detection purpose we used Viola Jones algorithm. To recognize face we worked with Eigen Faces which is a PCA based algorithm. In a real time to recognize a face we need a data training set. For data training set we took five images of each person and manipulated the Eig...

Received August 2, 2016 Revised October 7, 2016 Accepted November 1, 2016 Eigen faces (PCA) approach for face recognition. The face is an important part of which you are how people identify you. In face recognition there are two types of comparisons verification and identification. There are about 80 nodal points on a human face here are few nodal points that are measured by software that are d...
