Abstract

Quadtree representation presents many advantages in imageanalysis because of its better manipulation at different scales. In computervision one frequently faces the problem of multi-scale analysis. We use asyntactic representation of quadtree to analyse images in the Haar base withpyramidal algorithms in linear time. We present applications in dynamicfiltering, in compression and image segmentation.
