This paper presents a new segmentation technique for coloured images. It relies on building an irregular pyramid which presents only nodes associated to ho mogeneous colour regions. Segmentation is performed by rearranging the set of links among pyramid nodes. After segmentation process, several nodes placed at dierent pyramid levels may be regarded as roots of trees dened by its links to lower level nodes. These nodes dene a partition at the base of the structure. Unlike other hierarchical methods based on relinking procedures, our algorithm does not operate in an iter ative way and it preserves region connectivity.
