摘要
恶劣天气环境下拍摄的图像会受到雾或霾的影响,从而导致图像饱和度过低模糊、以及颜色灰白等负面效果,这不仅会使图像中的重要信息丢失,还会对后续计算机视觉任务(如目标检测、图像分割、人员再识别)的研究造成负面影响。为了解决上述问题,文章首先对图像去雾的发展历程进行分析和梳理,接下来重点论述了深度学习在图像去雾领域的研究进展,主要包含有监督去雾、无监督去雾和半监督去雾技术,并对各自的代表性算法进行深入对比分析。最后,介绍了图像去雾领域主流的数据集和评估指标。Images captured in harsh weather environments are often affected by fog or haze, which can lead to negative effects such as low saturation, blurring, and grayish-white colors. This not only results in the loss of important information in the image, but also has a negative impact on subsequent computer vision tasks such as object detection, image segmentation, and personnel re-identification. This article first provides a comprehensive analysis and sorting of image defogging and then reviews the research progress of deep learning in the field of image defogging, mainly including supervised defogging, unsupervised defogging, and semi-supervised defogging. We compared and analyzed representative algorithms among these methods. Finally, the commonly used datasets and evaluation metrics for image defogging were introduced.
