The performance of edge detection often relies on its ability to correctlydetermine the dissimilarities of connected pixels. For grayscale images, the dissimilarityof two pixels is estimated by a scalar difference of their intensities and for color images,this is done by using the vector difference (color distance) of the three-color components.
The Euclidean distance in the RGB color space typically measures a color distance.
However, the RGB space is not suitable for edge detection since its color componentsdo not coincide with the information human perception uses to separate objects frombackgrounds. In this paper, we propose a novel method for color edge detection bytaking advantage of the HSV color space and the Mahalanobis distance. The HSVspace models colors in a manner similar to human perception. The Mahalanobisdistance independently considers the hue, saturation, and lightness and gives themdifferent degrees of contribution for the measurement of color distances. Therefore, ourmethod is robust against the change of lightness as compared to previous approaches.
Furthermore, we will introduce a noise-resistant technique for determining imagegradients. Various experiments on simulated and real-world images show that ourapproach outperforms several existing methods, especially when the images vary inlightness or are corrupted by noise.
