A Comprehensive Review of Single Image Defogging Techniques used for Sea Fog Images

Abstract

Image Defogging is a well-addressed and challenging problem in the area of image processing. The foggy weather conditions in the atmosphere cause adverse effects on the images captured by the camera which in turn make it difficult to identify and detect the objects. Image defogging has many applications in the real world including traffic safety, remote sensing, agricultural monitoring, maritime surveillance, underwater imaging, etc. Based on these applications many defogging algorithms have been proposed in the past decades. Almost all defogging algorithms concentrate more on land images rather than ocean images. Fog removal from ocean images is more challenging than of removing fog from land images due to the atmospheric properties of fog in the sea. This paper mainly focuses on the study and review of various defogging approaches used for the removal of fog in ocean images. This work discusses some image-defogging techniques applied to ocean images, to get a clear vision of the images for various applications.
