Finding Junctions Using the Image Gradient
(1991-12-01)
Junctions are the intersection points of three or more intensity surfaces in an image. An analysis of zero crossings and the gradient near junctions demonstrates that gradient-based edge detection schemes fragment edges ...
Feature Extraction Without Edge Detection
(1993-09-01)
Information representation is a critical issue in machine vision. The representation strategy in the primitive stages of a vision system has enormous implications for the performance in subsequent stages. Existing ...
The Multi-Scale Veto Model: A Two-Stage Analog Network for Edge Detection and Image Reconstruction
(1992-03-01)
This paper presents the theory behind a model for a two-stage analog network for edge detection and image reconstruction to be implemented in VLSI. Edges are detected in the first stage using the multi-scale veto rule, ...
