Adaptive Contour Construction for Face Regions

Contours contribute much to object analysis in many applications. In this paper, an adaptive method of constructing face contours is proposed. First, a region splitting scheme is adopted to automatically generate grids over face regions. Based on the grids, initial face contours are then constructed. Finally, the contours are refined according to the minimum energy principle. Experimental results show that the proposed method has a good performance in face contour construction
