为解决传统暗通道不适用于大面积天空区域
容易造成去雾图像失真的问题
提出一种结合暗亮通道先验的远近景融合去雾算法。首先
利用改进的二维Otsu图像分割算法
混合近景和远景区域的暗通道
并基于最优的客观质量评价指标对近景和远景区域设置混合暗通道的自适应调节参数; 其次
针对真实物理场景中大气光并非均匀不变常量的问题
建立暗亮通道融合模型
并计算大气光图; 为了提升处理速度
在不降低恢复质量的前提下
选取与原图对应的灰度图作为引导图像对透射率图进行细化; 最后
采用基于视觉感知的亮度/颜色补偿模型对图像修正
提高了复原图像的对比度和色彩饱和度。实验结果表明
所提算法在主观和客观角度均取得最好的效果
其中客观指标PSNR在数值上比He的算法平均高出24.04%。由此得出
通过所提算法复原的图像更加清晰、细节信息和结构更加明显
更适于人眼的观察
验证了算法的有效性。
A far and near scene fusion defogging algorithm based on the prior of dark-light channel is proposed to solve the problem that traditional dark channel is not suitable for large sky area and it is easy to cause the distortion of dehazed image. Firstly
an improved two-dimensional Otsu image segmentation algorithm is utilized to mix the dark channels in the close and distant areas
and the adaptive adjustment parameters of the mixed dark channels are calculated based on the optimal objective quality evaluation index for the close and distant areas. Secondly
aiming at the problem that atmospheric light is not uniform and constant in real physical scenes
a dark-light channel fusion model is established to calculate the atmospheric light map. Furthermore
in order to improve processing speed
the grayscale image corresponding to the original image is selected as a guide image to refine the transmittance image without reducing restoration quality. Finally
the brightness/colour compensation model based on visual perception is used for image correction to improve the contrast and colour saturation of the restored image. Experimental results show that the proposed algorithm achieves the best results from both subjective and objective perspectives
in which the objective index PSNR is 24.04% higher than that of He's algorithm on average. It is concluded that the image recovered by the proposed algorithm is clearer
with more obvious details and structure
and is more suitable for human eyes to observe
which verifies the effectiveness of the algorithm.
