Bayesian Edge-Detection in Images via Changepoint Methods
David A. Stephens, A. F. M. Smith · Statisctics and computing/Statistics and computing · 1993
The problem of edge-detection in images will be formulated as a statistical changepoint problem using a Bayesian approach. It will be shown that the Gibbs sampler provides an effective procedure for the required Bayesian calculations. The use of the method for “quick and dirty” image segmentation will be illustrated.
