Although several colour edge detectors have been proposed, all of them utilized colour Euclidean distances in the colour space to measure colour differences. In this paper a set of colour edge detection algorithms based on colour visual perception is proposed. These algorithms are a combination of vector edge detector, in uniform colour spaces and using perceptual colour difference equations. A comparative study has been performed. To evaluate the detectors performance a set of synthetics images is generated and various measures are used. It can be concluded that detectors based on CIEDE2000 colour difference equation are better regarding the correlation with colour visual perception.
