基于Retinex理论的Mccann99算法改进

摘要

针对Mccann99算法在处理图像中的一些缺陷,提出了一种基于Retinex理论的Mccann99改进型算法.在改进中重新设定了Mccann99初始值,调整了差值,提出了新的循环次数,同时通过拓展图像的方式扩大了该算法的适用范围.实验结果表明,改进后的算法对图像的处理效果优于传统Mccann99算法.%Aiming at the weakness of Mccann99 in dealing with images, this paper develops a new method for image enhancement using Mccann99 algorithm based on Retinex theory. The initial value,D-value and the number of circle have been adjusted in the improvement. At the same time,the suitable range has been extended by the method of image expanding. The result of experiment shows that this algorithm is better than the traditional Mccann99 algorithm in enhancing image.
