Paper Abstract

An algorithm is presented capable of extracting homogeneous regions from an image based on multi-resolution processing. The algorithm is based on applying a local clustering at each resolution level of a linked pyramid data structure allowing seed nodes to be defined. These seed nodes are compact descriptions, roots nodes, of regions at the base of the pyramid, appearing in the multi-resolution data structure at a level appropriate to their size. Without a priori knowledge accurate segmentations are obtained by applying a merging process followed by a classification step. Results show the accuracy of the algorithm for a range of images, even in low signal to noise ratios.
