Definition
Color similarity is a measure that reflects the strength of relationship between two colors.
Background
A measure of similarity between colors is needed when one color region is matched to another region among color images, for example, a purple region is more similar to a blue region than a green region. Therefore, the similarity between two colors is an important metric in not only color science but also imaging science and technology (including computer vision). If color similarity is measured, it allows people to determine the strength of relationship in terms of numerical values; otherwise, it will be determined in nonnumerical ways.
Thus, the benefit of color similarity is its application to various techniques of image analysis, such as noise removal filters, edge detectors, object classification, and image retrieval.
Theory
Color similarity is usually represented in the range of either interval [ − 1,...
