Espaços de cores uniformes são muito importantes na engenharia de cores, codificação de fontes de imagens e processamento de informações multimídia. Apesar de muitos esforços terem sido feitos sobre o assunto, a construção de um espaço de cores exato e uniforme parece difícil até agora. As abordagens existentes usavam principalmente aproximações locais e heurísticas. Além disso, parecia também haver certa confusão nas definições dos espaços uniformes. Neste artigo discutimos a questão do ponto de vista da geometria Riemanniana global. A equivalência entre as definições globais e locais de espaço uniforme é mostrada. Em seguida, são apresentados um algoritmo exato e um simplificado para uniformizar uma parte ou a totalidade de um espaço de cores. Pode-se esperar que esses algoritmos encontrem aplicações na quantização ideal de informações de cores.

Abstract: Uniform color spaces are very important in color engineering, image source coding and multimedia information processing. In spite of many efforts have been paid on the subject, however, construction of an exact uniform color space seems difficult until now. Existing approaches mainly used local and heuristic approximations. Moreover, there seemed also certain confusion in definitions of the uniform spaces. In this paper we discuss the issue from a point of view of global Riemannian geometry. The equivalence between global and local definitions of uniform space are shown. Then both an exact and a simplified algorithm are presented to uniformize either a part or the totality of a color space. These algorithms can be expected to find applications in optimal quantization of color information.
