Face detection algorithm using EMD: Application to biometric recognition system

Abstract

In this work we present a new face detection algorithm for biometric recognition systems, based on Empirical Mode Decomposition (EMD) that helps us to detect the central skin part of the face. After a binarization and dilatation process, we get an approximation of the face location that is finally established by adjusting an ellipse. Finally, a mask is created using the perimeter of this ellipse and applied to the original image, giving as a result the detected face. Experiments show the performance of the method, with a recognition rate of 97.60%.
