Description Usage Arguments Details Value Author(s) See Also

View source: R/two_D.R

Description

Organizes the wavelet coefficients from a 2D DWT into a single matrix and plots it. The coarser resolutions are nested within the lower-lefthand corner of the image.

Usage

1
2
## S3 method for class 'dwt.2d'
plot(x, cex.axis = 1, plot = TRUE, ...)

Arguments

x

input matrix (image)

cex.axis

par plotting parameter that controls the size of the axis text

plot

if plot = FALSE then the matrix of wavelet coefficients is returned, the default is plot = TRUE

...

additional graphical parameters if necessary

Details

The wavelet coefficients from the DWT object (a list) are reorganized into a single matrix of the same dimension as the original image and the result is plotted.

Value

Image plot.
