Color Code Labels

Description

Color codes the labels of object masks by a random permutation.

Usage

colorLabels(x, normalize = TRUE)

Arguments

Details

Performs color coding of object masks, which are typically obtained using the bwlabel function. Each label from x is assigned an unique color. The colors are distributed among the labels using a random permutation. If normalize is set to TRUE the intensity values of the resulting image are mapped to the [0,1] range.

Value

An Image object containing color coded objects of x.
