plot.dwt.2d: Plot Two-dimensional Discrete Wavelet Transform

In waveslim: Basic Wavelet Routines for One-, Two-, and Three-Dimensional Signal Processing

Plot Two-dimensional Discrete Wavelet Transform

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

## 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.
