Plot of Two Dimensional Decomposition Result

Description

This function performs plotting of input image, IMF's, residue and extrema.

Usage

Arguments

z matrix of an image
emdz decomposition result
extrema specifies whether the extrma is displayed according to the level of IMF
... the usual arguments to the image function

Details

This function performs plotting of input image, IMF's, residue and extrema.

Examples

data(lena)
z <- lena[seq(1, 512, by=4), seq(1, 512, by=4)]
image(z, main="Lena", xlab="", ylab="", col=gray(0:100/100), axes=FALSE)
#lenadecom <- emd2d(z, max.imf = 4)
#imageEMD(z=z, emdz=lenadecom, extrema=TRUE, col=gray(0:100/100))
