摘要

带彩色恢复的多尺度视网膜皮层（MSRCR）去雾算法是解决雾、霾等恶劣天气下拍摄的图像的对比度下降和图像特征退化问题的一类算法

可以有效改善图像的视觉效果

但由于算法复杂度较高

实时处理困难。通过时域到频域的转化和基于TM320DM642本身硬件特性对MSRCR去雾算法进行了优化

并通过模拟仿真

实现了1024×1024视频的实时处理

得到令人满意的视觉效果。

Abstract

Multiple-scale retinex with color restoration（ MSRCR） is a defogging algorithm which can solve problem of contrast decline of image and degradation of image feature caused by haze and fog

it can effectively improves visual effect of image

but cannot ensure real-time processing due to high complexity of algorithm. Optimization is carried out on MSRCR algorithm based on hardware characteristics of TM320DM642 and transformation of time domain to frequency domain

achieve real-time processing of video with size of 1024 × 1024 by simulation and obtain satisfied visual effect.
