imageEMD: Plot of Bidimenasional Empirical Mode Decomposition Result

In EMD: Empirical Mode Decomposition and Hilbert Spectral Analysis

Description

This function draws plots of input image, IMF's, residue and extrema.

Usage

imageEMD(z = z, emdz, extrema = FALSE, ...)

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 draws plots 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)

## Not run: 
lenadecom <- emd2d(z, max.imf = 4)
imageEMD(z=z, emdz=lenadecom, extrema=TRUE, col=gray(0:100/100))
## End(Not run)
