A chromatic contour detector based on abrupt change techniques

Abstract

A method for segmenting colored iniages based on contour tletectioti is designed. It involves the use of techniques tiaseri O H nbriipt change detection used iii signal processing arid coritrol system. This \cork is based oti a theoretical fr-atiiervork : diferential geometq, tensors, ,Ve~~man-Pearsori's optimal decision. Good resitlts are obtained with gaiissiati and exporieritial noises. This method provides a veri, good location of contours.

New Robust Obstacle Detection System Using Color Stereo Vision

“…Cumani Cumani (1991) is the first to have use multidimensional gradients for detecting edges. Chapron Chapron (1992) Chapron (1997) used the Canny-Deriche gradient in each component. The DempsterShafer theory is used in Chapron (2000) for fusing the gradients.…”

“…The first research works into vector methods has used differential geometry to determine the rate of change and corresponding direction at each pixel Chapron (1997) Zugaj & Lattuati (1998). Other research has considered the use of probability distributions.…”

Cloud-Edge Suppression for Visual Outdoor Navigation

“…Edge-detecting procedures operating on color images can be divided into two groups: monochromatic-based and vector-valued techniques. Monochromatic-based techniques use classical edge-detection techniques on each color channel separately and then combine the individual results in a specific manner [21][22][23][24][25][26][27][28][29]. On the contrary, vector-valued techniques regard the color information as vectors [30][31][32][33][34][35][36].…”
