| 摘 要： | 针对MSR算法在图像去雾应用中存在颜色失真现象且计算量大的问题，提出一种具有颜色保真性的快速MSR去雾算法。通过将MSR算法对RGB三个颜色通道的处理转变为仅对暗原色单一通道进行处理，避免了对颜色通道间色调相关性的影响，实现颜色保真，同时大大减少了算法执行时间。实验结果表明该算法克服了MSR去雾算法的颜色失真问题，能够有效提升图像的对比度和饱和度，实现图像快速去雾。

| Abstract: | The multiscale Retinex algorithm has some drawbacks in the application of image haze removal, such as color distortion and high computation cost. A fast multiscale Retinex algorithm of image haze removal with color fidelity is proposed. Instead of processing three color channels, the proposed algorithm only processes on the dark channel, which avoids the influence on the tone correlation and reduces the running time. Experimental results are presented to demonstrate the performance of the proposed algorithm. |
