Quadtree representations for storage and manipulation of clusters of images

This article gives an overview of different approaches proposed for the storage and manipulation of clusters of images. Clustering images consists of grouping together images having a defined relationship. In this article, images are represented by quadtrees implemented in a hierarchical or linear way. The discussion, presented at the end of the article, allows selecting a quadtree-based representation well adapted to a specific area of application or to the characteristics of the manipulated images.ou
