Representation of segmented images with discrete geometric maps

摘要

Most models of representation of a segmented image have been designed to perform specific processing on images and are generally ill-adapted to other processes. Moreover, usually models describe separately the geometry and the topology of the regions of the image. Generally, this dichotomy makes it difficult or costly to design and implement operations involving both topological and geometrical features. In this paper, we give a complete description of a model encoding both geometry and topology of the region's of a segmented image. This model, based on inter-pixel boundaries associated with topological planar maps, has been successfully used for image segmentation.
