A proposed system for colorization of a gray scale facial image using patch matching technique

Abstract

This paper proposes a novel approach to colorize a gray scale facial image with the selected reference face using patch matching technique. The colorization methodology has been applied on facial images due to their extensive use in various important fields like archaeology, entertainment, law enforcement etc. The experiment has been conducted with 150 male and female facial images collected from different face databases and the result has been found satisfactory. The proposed methodology has been implemented using Matlab 7.
