Determining the orientation of surfaces from optical flow
This paper presents a method for computing the orientation of physical surfaces relative to the moving observer. The method is theoretically derived; it is not 'ad hoc'. The met...
The interpretation of a moving retinal image
It is shown that from a monocular view of a rigid, textured, curved surface it is possible, in principle, to determine the gradient of the surface at any point, and the motion o...
Optical Velocity Patterns, Velocity-Sensitive Neurons, and Space Perception: A Hypothesis
A hypothesis is put forward of how global patterns of optical flow, as discussed by Gibson, Johansson, and others, could be processed by relatively simple physiological mechanis...
Invariant Properties of the Motion Parallax Field Due to the Movement of Rigid Bodies Relative to an Observer
Abstract It is shown that the time-change of the natural perspective, due to the movement of rigid bodies relative to an observer, conveys information about geometrical properti...
Snakes, shapes, and gradient vector flow
Snakes, or active contours, are used extensively in computer vision and image processing applications, particularly to locate object boundaries. Problems associated with initial...
