Color edge detector using jointly hue, saturation and intensity
Thibault Carron, Patrick Lambert · 2002
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.>
