摘要: A robust pre-processing algorithm for lip segmentation is presented. We define a new transformation based on RGB color space: the chromatic curve map. It aims at increasing discrimination between lips and skin. allows detection under non uniform lighting conditions without any particular make-up. The motivation of present work to extract visual information automatic speech recognition, videoconferencing speaker's face synthesis natural conditions.
