【摘要】 修描(Inpainting)是用察觉不出的方法来修改图像的一种技术。图像修描的应用范围相当广泛，从受损油画和照片的恢复到所选物体的去除等。图像修描是图像复原中的一个新领域。目前在国内研究得还很少，而在国外，已受到不少图像处理研究人员的广泛重视。 本文在目前已有的几种修描方法的基础上，提出了一种基于欧拉弹性度和曲率的修描方法，并通过编译系统程序，实际演示进行了论证。与以前的方法相比，这里所介绍的技术克服了整体变分模型和Mumford-Shah模型中出现拐角和连通性不好的缺陷，从而使图像修描结果更加逼真完善。 论文从实用的角度出发，比较了图像修描的各种方法，在Windows平台上开发出了图像修描系统。该系统可作为Photoshop的一个插件用于图像处理中，进而减少了通常图像处理软件中进行人工修描的工作量，这种自动实现修描的算法，大大提高了工作效率，减少了工作时间。这对于图像处理工作站、印前图像处理还是家庭个人娱乐都提供了更多的兴趣和方便。更多还原

【Abstract】 Inpainting is a technique of modifying an image in an undetectable form. The goals and applications of inpainting are numerous, from the restoration of damaged paintings and photographs to the removal/replacement of selected objects. Image inpainting is a new area of Image restoration. Recently, there is little domestic research; however, it is regarded by many researchers in Image Processing area overseas.The paper introduces a new inpainting method that bases Euler’ s elastica and curvature, according to some forms recently. At same time, I program a system for demonstrating it. In contrast with previous approaches, the technique here introduced conquers the shortcoming of artificial corner and non-connectivity of TV model and Mumford-Shah model, and makes image more vivid and perfect.Set off from practicality, the paper has compared every method of image inpainting and developed a system of image inpainting on Windows platform. The system may be a plug-in to Photoshop during image processing. This automatic algorithm can improve work efficiency and decrease work time. This is very interesting and convenient not only to image processing workshop or prepress, but also to family person.更多还原
