Face recognition based on fuzzy probabilistic SOM

Face recognition is a topic of great interest in different areas, especially those related to security. The identification of a person by the image of her face is a difficult task because of changes experienced by the face due to various factors, such as facial expression, aging and even the lighting. This paper presents a new face recognition technique based on the combination of a competitive fuzzy neural network and a probabilistic decision criterion. The results of this technique on two images database offer satisfactory results. We also discuss the limitations of the proposed technique and future research lines.
