处理图象分析中的不确定性也是专家系统不可回避的任务.目前有多种用以表示不确定性,并能进行不精确推理的模型,主要有概率理论、证据理论和可能性理论;同时不精确推理的非数值方法也引起了人们的极大关注,如非单调逻辑.本文探讨了这些推理理论在一些具体图象分析问题中的应用途径. It is also an unavoidable task to deal with the uncertainty of image analysis.Nowadays, there are a variety of models for representing uncertainty and inaccurate reasoning, mainly including probability theory, evidence theory and probability theory. Meanwhile, Non-numerical inaccurate reasoning also aroused great attention, such as non-monotonic logic.This paper explores the application of these inference theory in some specific image analysis problems.
