Color edge detector using jointly hue, saturation and intensity

Abstract

In the hue saturation intensity (HSI) space, a hue difference taking into account the hue relevance is defined. A hue gradient operator is build up with this hue difference. Two color edge detectors are then proposed. These detectors mix in a different way H,S,I gradients. Experimental results are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
