Description

Modify coefficients by thresholding or shrinkage.

This function is generic.

Particular methods exist for the following objects:

wd object

the threshold.wd function is used;

imwd object

the threshold.imwd function is used;

imwdc object

the threshold.imwdc function is used;

irregwd object

the threshold.irregwd function is used;

wd3D object

the threshold.wd3D function is used;

wp object

the threshold.wp function is used;

wst object

the threshold.wst function is used.

Usage

Arguments

Details

See individual method help pages for operation and examples.
