摘要伴随着计算机技术、信息处理技术和视觉通信技术的高速发展，人类进入了一个全新的信息化时代。数字图像处理技术是信息处理技术的重要内容之一，在很多领域得到了越来越广泛的应用。对于数字图像一般要求是高分辨率图像，因此提高图像分辨率使图像获取领域里追求的一个目标。
本文主要着重于红外图像超分辨率算法研究。文章开始介绍了超分辨率的发展情况，然后介绍了红外成像系统的分类、组成部分、工作原理及影响红外图像分辨率的主要因素。从典型的红外成像系统数学模型出发，研究了目前常用的超分辨率算法。本文先介绍了常用的单帧图像超分辨率算法，总结了其优缺点。着重讨论运用POCS算法对红外低分辨率图像序列进行超分辨率处理。在对各种超分辨率算法进行探讨的基础上，对低分辨率红外图像序列进行灰度拉伸、双线性插值、基于特征的图像配准、POCS算法迭代运算处理，得到超分辨率图像。运用MATLAB进行了POCS算法的仿真实验，总结其优缺点，并提出改进。10851

Title Infrared image super-resolution algorithm
Abstract With the rapid development of computer technology, information processing technology and visual communication technology, people now are embracing a new information era. Digital image processing technology, one of the most important parts in information processing technology, has been applied broadly in different kinds of fields. Since high-resolution images are oftenly required, improving image's resolution is the goal in the field of image acquisition.
This paper chiefly emphasizes the algorithm research of infrared image's super-resolution. At the beginning of this paper, the development of image's super-resolution is introduced. Then, the paper introduces the sorts, composing parts, working principle of infrared imaging system and the main factors that effect infrared image's dimensional resolution. Based on the typical infrared imaging system's mathematical model, several kinds of common super-resolution reconstruction algorithms are discussed and compared. Firstly, we introduce super-resolution from a single image, together with its advantages and disadvantages. Secondly, depending on the discussion of different kinds of super-resolution reconstruction algorithms, we process the infrared image by gray stretching, bilinear interpolation, base-on-characteristics image registration, iterative computation with POCS, and end up with a super-resolution image.
Keywords infrared image, super-resolution, image reconstruction, POCS
