TLDR
In this paper, a novel edge detection algorithm for color images was described, in which smoothness of each pixel in color image is firstly calculated by means of similarity relation matrix and is normalized to maximum gray level.Abstract:
A novel edge detection algorithm for color images was described in this paper. In the proposed method, smoothness of each pixel in color image is firstly calculated by means of similarity relation matrix and is normalized to maximum gray level. In other words, color image in three-dimensional color spaces is mapped into one dimension. Accordingly the edges are performed in such a way that pixels lower than thresholds are assigned to be edge. Thus with proposed method, edge pixels in a color image are detected simultaneously without any complex calculations such as gradient, Laplace and statistical calculations.read more

TL;DR: In this article, a 3×3 quaternion mask is developed to filter out frequencies of the image in multiple directions and only provides details about the edges, which is more challenging than edge detection in gray-level images.

Features of Similarity
TL;DR: The metric and dimensional assumptions that underlie the geometric representation of similarity are questioned on both theoretical and empirical grounds and a set of qualitative assumptions are shown to imply the contrast model, which expresses the similarity between objects as a linear combination of the measures of their common and distinctive features.
