Web(Fog Aware Density Evaluator), based on natural scene statis-tics (NSS) and fog aware statistical features. However, no reference IQA is still an open issue and less reliable than FR-IQA. By contrast, the third class explores FR-IQA metrics to evaluate defogging methods. Due to a lack of real-world image pairs, the third class WebAug 10, 2024 · The researchers developed various computational intelligence algorithms for image defogging to improve the visibility of drivers. The main intention of this paper is to analyse the various types of foggy image and video databases with their pros and cons.
