| Popis: | 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. It allows robust lips detection under non uniform lighting conditions and without any particular make-up. The motivation of the present work is to extract visual information for automatic speech recognition, videoconferencing and speaker's face synthesis under natural lighting conditions. |
