Differential Operators for Edge Detection
(MIT Artificial Intelligence Laboratory, 1983-03)
We present several results characterizing two differential operators used for edge detection: the Laplacian and the second directional derivative along the gradient. In particular, (a)we give conditions for coincidence of ...
Microelectronics In Nerve Cells: Dendritic Morphology and Information Processing
(1981-10-01)
The electrical properties of the different anatomical types of retinal ganglion cells in the cat were calculated on the basis of passive cable theory from measurements made on histological material provided by Boycott ...
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 ...
