copula函数是把多维随机变量的联合分布用其一维边际分布连接起来的函数.基于著名的Sklar定理中联合分布函数与边际分布函数的关系,从图像重构的角度,提出广义copula的概念,并从理论上证明了它的存在性,给出了相关的性质,为广义copula的应用提供了相应的基础.

Copula is a function to link joint distribution functions and its margins.Based on the relationship between joint distribution functions and its margins stated by famous Sklar theorem,the present paper first gives the concept of extended copula from the view point of restructuring image and proves its existence and properties.It provides a basic theory for extended copulas application.
