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

本文 通过位平面分解法分割天空区域并运用椭圆最小二乘法拟合日周光散射光圈,并自动确定日周光的中心,将中心点的亮度与天空区域平均亮度的加权值作为最终提取的天空亮度值 最后运用大气散射模型对雾天降质图像进行复原-In t his paper , we segment t he sky area by bit2plane decomposition , and fit circadian light scat tering ring using elliptical least squares

CVPR2012_oral Micro Phase Shifting-We consider the problem of shape recovery for real world scenes, where a variety of global illumination (in- terreflections, subsurface scattering, etc.) and illumi- nation defocus effects are present. These
