Detect the possible spokesperson with an omni-directional camera, in a robot-human communication system

When the man-machine communication system faces many users at the same time, it becomes a question that how to discover the spokesperson. In the complex environment, the noise may cause some difficulties for the robot to recognize the sound commands. To solve this question, we try to use the camera on the robot to find out the spokesperson. In this research, we propose a new image processing method that using omni-directional camera. The robot may find out all the possible s spokesperson around it, by detecting the human body and its movement.
