一种基于小波融合的雾天视频监控图像增强算法

针对雾天视频监控系统采集的图像对比度降低、图像模糊的问题，提出一种小波融合算法。该算法在已有的图像增强方法的基础上，应用小波变换、直方图均衡化和非线性增强算子来综合处理雾天降质图像。实验结果表明，该算法对比于传统的方法不但可以明显的提高图像对比度，而且增强图像的边缘细节和纹理特性，取得较好的效果。

An Image Enhancement Algrorithm of Wavelet Foggy Video Surveillance Based on Fusion

In view of problems of low in contrast gradient and fuzzy in imaging quality when video monitoring system acquiring image in fog, propos-es an algorithm based on wavelet fusion. Uses wavelet transform, histogram equalization and non-linear operator to process synthetically fog-degraded image based on the existent image enhancement method. The experiments show that the algorithm compared with conven-tional methods can not only obviously improve image contrast and enhance the image edge details and texture property, and achieve good results.
