DSHDEN

shearlet denosing

Description

[RECX,THRESCOEFF]=DSHDEN(X,THR,R,BETA,BASISCHOICE,LEVEL,CG,ERR,ITS). shearlet denoising. INPUT X - Noisy image

  thr    - threshold

  R      - oversampling rate, default R = 2;

  beta   - scaling factor, default beta = 4;

basisChoice- weighting basis matrix, see BASISFUNCTION

  level  - decomposition level

  CG     - if CG == 1, use CG iteration to get the inverse
           else, use Adjoint

  err    - error control in the CG.

  its    - iteration total number

OUTPUT

  recX       - reconstructed image

  ThresCoeff - shearlet coefficient of X.
