数字图像修复技术是图像恢复领域的一个重要分支,它的目的是根据图像现有的信息来自动恢复丢失的信息,它可以用于旧照片中丢失信息的恢复、视频文字去除以及视频错误隐藏等。结合数字修复技术的图像压缩编码技术是基于对象的第二代图像编码中的研究热点之一。这里首先介绍了图像修复技术的概念,然后分类说明了几种常见的修复技术,在此基础上,得到了基于图像修复的压缩编码技术的基本处理流程,最后以具体算法为例说明了基于图像修复的压缩编码技术的压缩过程。
Digital image restoration technology is an important branch in the field of image restoration. Its purpose is to automatically recover the lost information according to the existing information of the image. It can be used for the recovery of lost information in old photos, video text removal and video error concealment . The image compression coding technology combined with digital repair technology is one of the hot topics in the research of object-based second-generation image coding. Here we first introduce the concept of image restoration technology, and then classify several common repair techniques. Based on this, we get the basic processing flow of image compression based on image restoration. Finally, we illustrate the algorithm based on image Fix the compression process of compression coding.
