摘要
根据噪声的先验特点 ,建立了基于 Markov随机场的退化图像恢复模型 ,从而将图像的恢复问题转化为求解最大后验概率 ( MAP)的问题。本文以模拟退火算法的思想为基础 ,通过引入随机判据的方法代替退火过程来进行 MA P的估计 。
According to the characteristics of the noise, we build up a restoration model of the degenerated image based on Markor, and then transform the problem of image restoration into finding the maximum a posteriori Based on the simulated annealing algorithm,we use a new method of random criterion to estimate the MAP, and the experiment result is satisfying
