摘　　要：图像放大技术是一种常见的重要的数字图像处理技术.本文从TV模与几何上曲率联系的角度,采用一种新的基于TV模的方法对图像放大过程中所新增加的数据进行处理,并且结合Matlab的剪裁函数imcrop,简易地实现了对图像特定区域的放大.Zooming in is a kind of familiar and important numerical picture processing technique, this literary not only present a kind of TV norm method having the meaning in curvature in order to handle the interpolation, but also adjust to use the imcrop in the Matlab processing toolbox , in order to carried out simply to the particular block to be selection , This paper present a kind of new method to realization zoom in particular block in the picture.
