Zero-Crossings and Spatiotemporal Interpretation in Vision
(1982-05-01)
We will briefly outline a computational theory of the first stages of human vision according to which (a) the retinal image is filtered by a set of centre-surround receptive fields (of about 5 different spatial sizes) ...
On Edge Detection
(1984-08-01)
Edge detection is the process that attempts to characterize the intensity changes in the image in terms of the physical processes that have originated them. A critical, intermediate goal of edge detection is the detection ...
The Implicit Constraints of the Primal Sketch
(1981-10-01)
Computational theories of structure-from-motion and stereo vision only specify the computation of three-dimensional surface information at points in the image at which the irradiance changes. Yet, the visual perception ...
