摘要
Various methods for lip segmentation have been proposed, it still remains a challenging and difficult problem due to high variability of lip color and low chromatic contrast between the lip and skin. A novel automatic lip segmentation algorithm is proposed based on a novel color transformation in RGB space instead of complex color models. Comparative study with some existing lip segmentation algorithms has indicated the superior performance of the developed algorithm. The proposed algorithm produces better segmentation fast and efficiently.
