On active camera control with foveate wavelet transform

In this paper, a new variable resolution technique, foveate wavelet transform (FWT), is introduced to represent video frames in an effort to emulate the animate vision systems. Compared to the existing variable resolution techniques, the strength of the proposed scheme encompasses its flexibility and conciseness while supporting interesting behavior resembling the animate vision system. With the FWT as the representation, an efficient scheme to achieve purposive vision is developed. The foveate potential motion area is first labeled, the camera motion is then determined by following the labeled moving object. Experiments based on our computer-controlled pan-tilt-zoom camera have demonstrated its efficacy in real-time active camera control
