Abstract

We propose a multi-camera system that can track multiple human faces and hands as well as focus on them for face and hand-sign recognition. Our current system consists of four video cameras. Two cameras are fixed and used as a stereo camera to estimate position. The stereo camera detects faces and hands using a standard skin color method we proposed. The distances of targets are then estimated. To track multiple targets, we evaluated position and size of targets in consecutive frames. The other two cameras perform target tracking. Our system selects a target for recognition by using size and motion information sequentially. If size of the selected target is too small for recognition, tracking cameras acquire its zoomed image. Using our system, we experimented on multiple target tracking.
