plot.imageQT: A plot function for quadtree decompositions.

Description

A plot function for quadtree decompositions.

Usage

# S3 method for imageQT
plot(x, cires, unclassval = 0, class = FALSE, QT = TRUE, 
		return = FALSE, qtl = 1, ...)

Value

immat

the matrix associated to the plotted image.

Arguments

x

A quadtree decomposition object, such as output from imageQT.

cires

Results of countTextures for the classification of subimages produced by the quadtree decomposition.

unclassval

A value for unclassified values in a quadtree decomposition.

class

A boolean value indicating whether to plot the results from countTextures.

QT

A boolean value indicating whether to plot the quadtree decomposition.

return

A boolean value indicating whether to return the matrix associated to the plotted image.

qtl

Colour specification for the lines drawn in the image segmentation (for QT=TRUE).

...

Any other optional arguments to image.

Details

The function plots the chosen quadtree decomposition, and optionally the textured region classification output from countTextures. If the classification output is plotted (class=TRUE), each textured region is uniquely coloured according to its texture group.

Examples

if (FALSE) {

X<-simTexture(256,K=1,imtype="NS2")[[1]]

XQT<-imageQT(X, bs=100, smooth=FALSE)

XCI <- Tex(XQT$imS, bs=100, smooth=FALSE)

plot(XQT, XCI, QT=T, class=T)
