为改善雾天拍摄图像的清晰度,提出一种实用的图像去雾方法。先利用暗原色先验算法去除图像雾干扰,再运用插值抠图算法进一步改善图像去雾效果,最后利用图像的区间值信息对其进行放大,以便获得满意的视觉效果。实验结果表明,该去雾方法不仅可直接估计雾的浓度,并且可得到去雾后的高清晰图像。
為改善霧天拍攝圖像的清晰度,提齣一種實用的圖像去霧方法。先利用暗原色先驗算法去除圖像霧榦擾,再運用插值摳圖算法進一步改善圖像去霧效果,最後利用圖像的區間值信息對其進行放大,以便穫得滿意的視覺效果。實驗結果錶明,該去霧方法不僅可直接估計霧的濃度,併且可得到去霧後的高清晰圖像。

In order to improve the sharpness degree of images captured in the condition of foggy weather,an useful defogging method for image is proposed.First,a dark channel prior algorithm is utilized to remove the fog interference from a single input image.Then it uses a soft matting interpolation algorithm to further improve the image effect.Finally,the interval information of image is used to magnify the images in order to obtain satisfactory visual effect of the image.The experimental results show that the defogging method proposed can not only directly estimate the concentration of the fog,but also recovery remove fog interfere with a clear image of high-quality.
