Human Face Detection

Abstract

Face Detection is fast becoming a familiar feature in various technical fields such as video surveillance, military applications, apps and on web, potentially making life easier for us. In current era of social networking Face Detection is a hot topic of research in both academics and commercial area throughout the world. Quite interestingly, the variation in the human skin colour between different races existing in this world primarily is the intensity that is proportional to the amount of melanin in the skin. So our approach towards face detection which uses skin colour seems effective since the skin colour database for various races can easily be collected. In our project, we have studied and worked on face detection techniques and developed an algorithm that detects human faces in an image. Our algorithm identifies possible skin regions in an image and using the skin colour spread in the whole image detects faces. We have taken our own still images as examples and simulated the algorithm in MATLAB 7.10.0 successfully.
