图像复原技术概述。对图像复原技术的概念、起源和发展过程做以概述，

详细介绍了国内外图像复原经典算法和研究现状。由于户外图像的退化与大气

状况密不可分，分析了光在传输的过程中发生散射和衰减的物理过程。为接下

来的图像复原工作提供了理论基础。-Overview of image restoration techniques. The concept of image restoration techniques, the origin and development process in order to do an overview, details of the domestic and international image restoration algorithm and the classic study of the status quo. As the outdoor atmospheric conditions and the degradation of the image are inseparable, analysis of light transmission occurs during the physical process of scattering and attenuation. Work for the next image restoration provides a theoretical basis.
