摘要
基于HSI(Hue, Saturation and Intensity)颜色空间提出一种快速偏振光学去雾方法。利用HSI颜色空间中强度与颜色无关的优势,在强度通道中利用偏振光学去雾方法进行去雾处理,然后利用颜色恒常性校正方法对图像的颜色畸变进行校正。该技术不仅具有良好的图像细节恢复能力,还有效地提高了偏振光学去雾方法的计算效率。与目前流行的去雾方法进行对比后可知,该技术可以得到更好或者相同的实验效果,但其执行效率更高。所提出的方法在图像实时去雾和视频去雾领域有广阔的应用前景。
Abstract
We propose a fast polarimetric dehazing method based on the hue, saturation, and intensity color space. Because the intensity is unrelated to color in the HSI color space, the proposed method is used to dehaze the intensity channel of an image, while its color distortion is corrected using a color-constancy method. This method not only shows good image-information restoration capacity but also increases the dehazing efficiency. Compared with the existing dehazing methods, the proposed method can obtain the same or better experimental results and has higher execution efficiency. Our proposed method has potential in applications for real-time haze removal in images and videos.
