The elicitation of power priors, based on the availability historical data, is realized by raising likelihood function data to a fractional δ, which quantifies degree discounting information in making inference with current data. When δ not pre-specified and treated as random, it can be estimated from using Bayesian updating paradigm. However, original form joint prior approach, certain positiv...

Partitioning of a graph representation, defined over low-level image features based on Gestalt inspired relations, is an effective strategy for forming coherent perceptual groups in an image. The usual practice, mainly motivated by efficiency considerations, is to approximate the general K-way partitioning solution by recursive bi-partitioning, where at each step the graph is broken into two pa...
