基于半逆法的彩色图像光晕快速消除方法

Fast elimination method of color image halo based on semi inverse method

传统的彩色图像光晕消除方法计算量过大,各个环节之间衔接不够紧密,导致消除过程慢,消除结果差。为了解决此问题,基于半逆法研究了一种新的彩色图像光晕消除方法,对消除过程进行了重点设计,并对每一步进行阐述。在消除彩色图像光晕之前,首先要估算彩色图像背景颜色,分析各个颜色参量,然后找出产生光晕的局部区域,调节颜色对比度,接着通过控制系统和异常应对系统消除彩色图像的光晕,最后对图像上含有光晕的区域做颜色恢复处理。与传统消除方法进行实验对比,结果表明,基于半逆法的彩色图像光晕消除方法能够简化计算量,提高消除过程,改善消除结果。本研究对于图像处理有重要的指导意义。

The traditional method of color image halo elimination has too much calculation,and the links between the links are not close enough,resulting in slow elimination process and poor results.In order to solve this problem,a new halo elimination method of color image based on semi-inverse method is studied.The process of halo elimination is designed and each step is described.Before eliminating the halo of the color image,the background color of the color image should be estimated,and the color parameters should be analyzed.Then the local area of the halo should be found out,and the color contrast can be adjusted.Then the halo of the color image can be eliminated by the control system and the abnormal coping system.Finally,the area containing the halo in the image should be restored.Complex treatment.The experimental results show that the halo elimination method based on semi-inverse method can simplify the calculation,improve the elimination process and improve the results.This study has important guiding significance for image processing.
