Restricted equivalence functions are well-known
functions to compare two numbers in the interval between 0
and 1. Despite the numerous works studying the properties of
restricted equivalence functions and their multiple applications
as support for different similarity measures, an extension of these
functions to an n-dimensional space is absent from the literature.
In this paper, we present a novel contribution to the restricted
equivalence function theory, allowing to compare multivalued
elements. Specifically, we extend the notion of restricted equivalence functions from L to L
n
and present a new similarity
construction on L
n
. Our proposal is tested in the context of
color image anisotropic diffusion as an example of one of its
many applications.
