一种改进的容差机制图像去雾算法
Improved haze removal algorithm based on tolerance mechanism
摘要
Abstract
In view of the problem that exists in the classic tolerance mechanism image haze removal al-gorithm,the efforts to enhance the transmission of the bright region is not enough,it is difficult to completely eliminate the color distortion,an improved algorithm is proposed herein.For the bright re-gion transmission,according to the tolerance,hyperbolic type enhancement is adopted in the original algorithm,while linear enhancement correction is used in this paper,which makes the transmission enhance steadily.The effort to enhance the transmission is appropriately increased,thus the color dis-tortion is effectively eliminated.Variance and color reduction degree are used as objective quality eval-uation index for image haze removal.Compared with the dark channel prior algorithm and the classic tolerance mechanism algorithm,the proposed algorithm is superior to the contrast algorithms in im-proving the color distortion of the bright region and improving the image haze removal.关键词
