Ant Algorithms for Adaptive Edge Detection
Aleksandar Jevtić, Bo Li · InTech eBooks · 2013
Edge detection is a pre-processing step in applications of computer and robot vision. It transforms the input image to a binary image that indicates either the presence or the absence of an edge. Therefore, the edge detectors represent a special group of search algorithms with the objective of finding the pixels belonging to true edges. The search is performed following certain criteria, as the edge pixels are found in regions of an image where the distinct intensity changes or discontinuities occur (e.g. in color, gray-intensity level, texture, etc.).
