Parallel implementation of a face location algorithm based on the hough transformation

In order to localize the face in an image, our approach consists to approximate the face oval shape with an ellipse and to compute coordinates of the center of the ellipse. For this purpose, we explore a new version of the Hough transformation : the Fuzzy Generalized Hough transformation. To reduce the computation time, we present also a parallel implementation of the algorithm on 2 Digital Signal Processors and we show that an acceleration of factor 1.6 has been obtained.
