| 中文摘要: |
| 受粉尘、低照度或点光源等因素影响，城市道路下穿立交监控图像存在对比度低、背景噪声强和整体视觉效果不理想等问题。针对这类问题，本文提出了一种改进的带色彩恢复的多尺度视网膜增强(MSRCR)算法，并且详细分析了改进的MSRCR 算法的原理和实现方法。为验证本文算法的有效性，以实际采集的4 幅彩色图像为实验样本，分别利用SSR(单尺度Retinex)算法、MSRCR 算法和本文算法对其进行了增强处理。实验结果表明，与对比算法相比，本文算法具有更大的优势。 |

| Due to the factors such as dust，low illumination，and pointolit，the monitoring images on the urban road of underpassing interchanges bear the problems such as low contrast，strong background noise，and overall poor visual effects and so on. In this paper，an improved Multi-scale retinex(MSRCR) algorithm with color restoration is proposed，and the principle and implementation of the improved MSRCR algorithm are analyzed in detail.. In order to verify the validity of this algorithm，the four color images collected are used as experimental samples，which are enhanced with SSR(single scale Retinex) algorithm，MSRCR algorithm and the proposed algorithm in this paper.The experimental results show that compared with the comparison algorithm，this proposed algorithm in this paper has more advantages. |
