Among a wide variety of sensing technologies vision systems are capable to derive a mobile robot’s relationship and orientation with respect to the surrounding environment. In this paper, we present an algorithmic approach to derive sensor orientation from image sequences acquired by a binocular vision-based mobile “robot”, which moves in an office, sensing its environment. The data acquisition...

We evaluated orientation discrimination in color and luminance vision using an external noise paradigm. Stimuli were spatiotemporal patches of 2D orientation noise isolating the achromatic, red-green and blue-yellow mechanisms, and matched in multiples of contrast detection threshold. We found a monotonic increase of orientation discrimination thresholds with the stimuli orientation bandwidths ...

Orientation disparity, the difference in orientation that results when a texture element on a slanted surface is projected to the two eyes, has been proposed as a binocular cue for 3D orientation. Since orientation disparity is confounded with position disparity, neither behavioral nor neurophysiological experiments have successfully isolated its contribution to slant estimates or established w...
