threshold.imwdc
Threshold two-dimensional compressed wavelet decomposition object
DESCRIPTION
This function provides various ways to threshold a
imwdc class object.
USAGE
threshold.imwdc(imwdc, verbose=F, ...)
REQUIRED ARGUMENTS
- imwdc
- The two-dimensional compressed
wavelet decomposition object that you wish to
threshold.
OPTIONAL ARGUMENTS
- verbose
- if TRUE then the function prints out informative messages as it progresses.
- ...
- other arguments passed to the threshold.imwd
function to control the thresholding characteristics such as
policy, type of thresholding etc.
VALUE
An object of class imwdc if
the compression option is supplied and set to TRUE, otherwise a
imwd object is returned. In either case the
returned object contains the thresholded coefficients.
Note that if the
return.threshold option is set to TRUE then the threshold
values will be returned rather than the thresholded object.
SIDE EFFECTS
None
DETAILS
This function performs exactly the same function as
threshold.imwd except is accepts
objects of class imwdc rather than
imwd. Indeed, this function physically
calls the threshold.imwd function after
using the uncompress function to
convert the input imwdc object
into a imwd object.
