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

threshold(...)
