Today, wireless sensor networks encompass a wide volume of applications. In these networks, nodes consist of limited energy. Therefore, we must be able to save in their energy usage. Protocol TDMA in these networks is a ...

Lip detection is used in many applications such as face detection and lips reading. We have proposed a novel approach for detecting lip using particle swarm optimization (PSO). PSO is used to obtain an optimized map. The image is mapped to Y Cb...
