Adaptive multiresolution analysis based on anisotropic triangulations
A simple greedy refinement procedure for the generation of data-adapted triangulations is proposed and studied. Given a function f of two variables, the algorithm produces a hierarchy of triangulations (Dj)j≥0 and piecewise polynomial approximations of f on these triangulations. The refinement procedure consists in bisecting a triangle T in a direction which is chosen so as to minimize the loca...
متن کاملAdaptive multiresolution analysis based on synchronization.
We propose an adaptive multiscale approach to data analysis based on synchronization. The approach is nonlinear, data driven in the sense that it does not rely on a priori chosen basis, and automatically determines the data scale. Numerical results for one- and two-dimensional cases illustrate that the method works effectively for the usual modulated signals such as chirps, etc., as well as for...
متن کاملA Real Time Adaptive Multiresolution Adaptive Wiener Filter Based On Adaptive Neuro-Fuzzy Inference System And Fuzzy evaluation
In this paper, a real-time denoising filter based on modelling of stable hybrid models is presented. Thehybrid models are composed of the shearlet filter and the adaptive Wiener filter in different forms.The optimization of various models is accomplished by the genetic algorithm. Next, regarding thesignificant relationship between Optimal models and input images, changing the structure of Optim...
متن کاملAdaptive Mammographic Image Feature Enhancement Using Wavelet-Based Multiresolution Analysis*
This paper presents a novel and computationally efficient approach to an adaptive mammographic image feature enhancement using wavelet-based multiresolution analysis. Upon wavelet decomposition applied to a given mammographic image, we integrate the information of the tree-structured zerocrossings of wavelet coefficients and the information of the low-pass filtered subimage to enhance the desir...
متن کاملMixture models based on Multiresolution Analysis Theory
The aim of this paper is to define a new family of probability density functions (MR pdf) based on the multiresolution analysis theory. Each function of this family can be seen as a particular type of density mixture. The MR pdf has advantages of estimation over the conventional mixtures and it is suitable to model a large variety of square integrable probability density functions. The flexibil...
