This paper proposes a relaxation-based algorithm for detection of facial features such as face outline, eyes, and mouth. At first, a number of candidates for each facial feature are detected. To select a correct set of facial features from the candidates, probabilities and geometric relationships of each candidate location are considered, in which a relaxation algorithm is used for implementation. Simulation results with various test images are presented.
