plotBD: Visualization of posterior boundary estimates and data

In BayesBD: Bayesian Inference for Image Boundaries

Description

Produces plots of image data, posterior boundary estimates,
and 95

Usage

plotBD(fitted.image, plot.type)

Arguments

fitted.image	An object containing the output of either fitBinImage or fitContImage.
plot.type	takes values 1, 2 or 3: 1 to plot the data only; 2 to plot the estimate and 95% uniform credible bands; and 3 to plot the data with the estimated boundary overlaid.

Value

There is no output to console; plotBD produces plots.
