Binocular fixation on wide-angle foveated vision system contour-based feature generation from space-variant image using DFT

This paper introduces a novel interactive vision system, which is suitable for cooperative works between the human and computer. This system acquires human-like binocular wide-angle foveated (WAF) information from a stereo camera head with special wide-angle optical lens and provides processed video signals both to the computers and to the user's sight simultaneously. The user can observe this unique information on 3D head mount display (HMD). The developed vision system is quite applicable for the human brain and vision research like psychophysics, because it has two kinds of loop, which are biology and computational. In the system implementation, binocular fixation provides well-fused 3D images to the user. This paper proposes to carry out it based on features extracted from contour images, and examines about scale, rotation and translation (SRT) invariant features generated from WAF space-variant images using Discrete Fourier Transform (DFT).
