BlockThresh2d: 2d Wavelet Block thresholding

In fabnavarro/rwavelet: Wavelet Analysis

2d Wavelet Block thresholding

Description

This function is used to threshold the coefficients by group (or block).

Usage

BlockThresh2d(
  wc,
  j0,
  hatsigma,
  L = 4,
  qmf,
  lamb = 4.50524,
  thresh = "JamesStein"
)

Arguments

wc	wavelet coefficients.
j0	coarsest decomposition scale.
hatsigma	estimator of noise variance.
L	Block size (n mod L must be 0).
qmf	Orthonormal quadrature mirror filter.
lamb	Threshold parameter.
thresh	Thresholding rule: 'hard', or 'JamesStein'.

Value

wcb Thresholded wavelet coefficients.
