COMBINATION MEDIAN FILTER BASED ON BAYES-DECISION
基于Bayes决策的组合中值滤波

To settle the contradiction of noise-filtering and image detail-preserving in image filtering, a combination median filter based on Bayes-decision is proposed. The main contributions are: (1) deriving the union conditional density function of a defined test vector; (2) giving an algorithm for estimating pre-probability; (3) introducing a new filter structure, which combining median and multistage median filters based on Bayes-decision.
