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
plot.dwt.2d(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
Value
Image plot.
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.
