An approach for Fuzzy Dominant Color Descriptor
J. Chamorro-Mart ́ õnez, Jose Manuel Soto-Hidalgo, P. Mart · 2011
In this paper, a new Dominant Color Descriptor is proposed. This descriptor is defined as a fuzzy set over a finite universe of fuzzy colors, in which membership degrees represent the dominance of each color. The fuzzy colors employed are fuzzy sets defined on an ordinary color space, filling the semantic gap between the color representation in computers and its human perception. The dominance of each fuzzy color is calculated on the basis of a fuzzy quantifier representing the notion of dominance, and a fuzzy histogram representing as a fuzzy quantity the percentage of pixels that match each fuzzy color. The obtained descriptor can be employed in a large amount of applications. We illustrate the usefulness of the descriptor by a particular application in image retrieval.
