摘要

本文的主要目的是在给定向量场约束下，建立变分模型在图像分割中的存在性结果。在一维情况下，我们给出了一个离散版本以变分的方式收敛于连续模型。最后给出了该模型在图像分割中的应用。

Variational approximation of a constraint signal by a Mumford-Shah type energy functional

In this paper, the main objective is to establish an existence result of a variational model in image segmentation constrained by a given vector field. In the one dimensional case, we give a discrete version converging in a variational way to the continuous model. We finally describe the numerical analysis of this model with application in image segmentation.
