We provide a framework for structural multiscale geometric organization of graphs and subsets of R(n). We use diffusion semigroups to generate multiscale geometries in order to organize and represent complex structures. We show that appropriately selected eigenfunctions or scaling functions of Markov matrices, which describe local transitions, lead to(More)
In the companion article, a framework for structural multiscale geometric organization of subsets of R(n) and of graphs was introduced. Here, diffusion semigroups are used to generate multiscale analyses in order to organize and represent complex structures. We emphasize the multiscale nature of these problems and build scaling functions of Markov matrices(More)
Is proposed a method for the automatic detection of dark fibres in wool tops based on image processing. A software which implements this method was developed, composed by five modules: KL projection , light correction, Gabor filtering, segmentation and morphology. The digital image are taken by a camera placed in a balanced illumination system. The method(More)
