Abstract :
A new variable resolution technique-foveate wavelet transform (FWT)-is proposed in this paper to represent images in an effort to emulate the animate visual systems. With the FWT representation and a simplified configuration of the stereo rig, efficient disparity-based algorithms to achieve gaze control of the rig are developed. With these algorithms, the attention of the stereo rig can be centered around the object of most interest with desired resolution for both the static and moving objects. Experiments based on the algorithms have demonstrated their efficacies in the gaze control of the stereo rig
