摘要
Retinex算法是彩色图像增强领域中的重要方法,Retinex算法具有丰富的内涵.针对传统Retinex算法易在增强结果中产生色彩失真、光晕现象等局限性,本文讨论并分析了现有的基于颜色空间转变、色彩校正和估计照度分量设计方法的一系列相关的改进方法.最后指出了Retinex算法可进一步研究的方向.
Retinex algorithm is an important method in the field of color image enhancement,and it has rich connotation.Aiming at the limitations of traditional Retinex algorithm in color distortion and halo,the paper discusses and analyzes a series of related improved methods based on color space transformation,color correction,and estimated illumination component design.Finally,the further possible research directions of Retinex algorithm are pointed out.
