Olena Alexandre Abraham. Morphology on Color Images. CSI Seminar 0835 January 2009

This work takes place in the context of Milena, the C++ generic image processing library of the Olena platform, developed at LRDE. Morphological algorithms are one of Milena's major assets. Yet few image processing libraries implement them even though they are very useful. Those algorithms require supremum and infimum operators, which don't exist by default for composite types like red-green-blue (RGB) pixels. We therefore propose the implementation of those operators for RGB values, along with a complete toolchain allowing morphological algorithms to work on color images.

Les algorithmes morphologiques sont l'un des atouts majeurs de Milena, la biblioth\`eque de traitement d'images g\'en\'erique et performante d\'evelopp\'ee au LRDE. En effet, ils sont tr\`es utiles et relativement peu impl\'ement\'es dans les autres biblioth\`eques. Ces algorithmes requi\`erent des op\'erateurs de bornes sup\'erieure et inf\'erieure (\textit{supremum} et \textit{infimum}) qui n'existent pas par d\'efaut pour des types composites comme les couleurs encod\'ees en rouge-vert-bleu (RVB). Nous pr\'esentons donc une impl\'ementation de ces op\'erateurs pour le type RVB ainsi que toute la cha\^ine de traitement permettant de faire fonctionner des algorithmes morphologiques sur des images en couleurs.
