Les espaces colorimétriques uniformes sont très importants dans l’ingénierie des couleurs, le codage des sources d’images et le traitement des informations multimédia. Malgré les nombreux efforts déployés sur le sujet, la construction d'un espace colorimétrique exactement uniforme semble jusqu'à présent difficile. Les approches existantes utilisaient principalement des approximations locales et heuristiques. De plus, il semblait aussi y avoir une certaine confusion dans les définitions des espaces uniformes. Dans cet article, nous discutons de la question d’un point de vue de la géométrie riemannienne globale. L'équivalence entre les définitions globales et locales de l'espace uniforme est montrée. Ensuite, un algorithme exact et un algorithme simplifié sont présentés pour uniformiser une partie ou la totalité d'un espace colorimétrique. On peut s’attendre à ce que ces algorithmes trouvent des applications dans la quantification optimale des informations de couleur.

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.
