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.
# S3 method for dwt.2d
plot(x, cex.axis = 1, plot = TRUE, ...)input matrix (image)
par plotting parameter that controls the size
of the axis text
if plot = FALSE then the matrix of wavelet
coefficients is returned, the default is plot = TRUE
additional graphical parameters if necessary
Image plot.
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.
