Dehazing of Natural Images Using Volterra Based Non-Linear Filter
N. Tamil Selvi, Ashwani Kumar Dubey · 2018
When outdoor images are captured by a camera in bad weather conditions which yield poor visibility conditions, where noise is also present due to low contrast of an image, color variation which is a major issue for most computer vision applications. The hazy weather conditions, it blocks the dispersal of haze, smoke and other pollutions in the environment which leads to harm invisibility and respiratory health problems. In this paper, we proposed a Volterra based Non-Linear filters for image enhancement and image restoration in bad weather conditions. The linear filters help to reduce noise but it causes blurriness in the edges of the image. In case of Non-linear filters are dealing with impulsive noise which helps to preserve the edges of the image. So, the Volterra filter is designed to enhance the compact between unwanted noise reduction and edge preservation.
