摘要
提出一种改进的Retinex算法——基于单尺度Retinex的非线性图像增强算法.不同于经典的Retinex算法用复杂的运算估计亮度图像,该算法首先对亮度图像进行粗估计,然后通过非线性运算在反射图像中对粗估计的亮度图像进行补偿.实验结果表明,所提出的算法同经典的Retinex算法相比,无论在增强效果还是在处理时间上都具有更大的优越性.
A nonlinear image enhancement algorithm based on single scale retinex was proposed. Unlike classical retinex methods estimate the illumination image in a complex way, the proposed algorithm estimates the illumination image approximately, and then compensates the approximate estimation in a nonlinear way. Compared with classical retinex methods, the experimental results show that the proposed method can offer better performance not only in visual enhancement but also in fast processing.
