Nonlinear thresholding of multiresolution decompositions adapted to the presence of discontinuities
نویسندگان
چکیده
A new nonlinear representation of multiresolution decompositions and new thresholding adapted to the presence of discontinuities are presented and analyzed. They are based on a nonlinear modification of the multiresolution details coming from an initial (linear or nonlinear) scheme and on a data dependent thresholding. Stability results are derived. Numerical advantages are demonstrated on various numerical experiments.

Water hammer simulation by explicit central finite difference methods in staggered grids
Four explicit finite difference schemes, including Lax-Friedrichs, Nessyahu-Tadmor, Lax-Wendroff and Lax-Wendroff with a nonlinear filter are applied to solve water hammer equations. The schemes solve the equations in a reservoir-pipe-valve with an instantaneous and gradual closure of the valve boundary. The computational results are compared with those of the method of characteristics (MOC), a...
متن کاملApproximation of piecewise smooth functions and images by edge-adapted (ENO-EA) nonlinear multiresolution techniques
This paper introduces and analyzes new approximation procedures for bivariate functions. These procedures are based on an edge-adapted nonlinear reconstruction technique which is an intrinsically two-dimensional extension of the essentially non-oscillatory and subcell resolution techniques introduced in the one dimensional setting by Harten and Osher. Edge-adapted reconstructions are tailored t...
متن کاملProgressive and lossless image coding using optimized nonlinear subband decompositions
In super high-de nition image applications such as medical image archival, progressive and lossless coding is required since any degradation in the decompressed image is unacceptable. Recently, nonlinear subband decompositions have received much attention as they provide very compact multiresolution representations and they allow exact reconstruction of the input image. Within this framework, w...
متن کامل9 . Adaptive ENO - Wavelet Transforms for Discontinuous Functions
We have desiged an adaptive ENO-wavelet transform for approximating discontinuous functions without oscillations near the discontinuities. Our approach is to apply the one-side information idea from Essentially Non-Oscillatory (ENO) schemes for numerical shock capturing to standard wavelet transforms. This transform retains the essential properties and advantages of standard wavelet transforms ...
