In this paper, we discuss certain issues regarding robot vision. The m
ain theme will be the importance of the choice of information represen
tation. We will see the implications at different parts of a robot vis
ion structure. We deal with aspects of pre-attentive versus attentive
vision, control mechanisms for low level focus of attention, and repre
sentation of motion as the orientation of hyperplanes in mult-dimensio
nal time-space. Issues of scale will be touched upon, and finally, a d
epth-from stereo algorithm based on guadrature filter phase is present
