Deep-Water Image Enhancement by Guided Filtering

Abstract

Enhancement of deep-water or underwater images is necessary due to number of challenges that occurs because of the water medium that supports scattering, absorption and haziness. Enhancement of images has used a technique that will be done using box filtering and guided filtering that preserves the edge factor and smoothens the image which will undergo dark channel prior algorithm to clear the hazes in the image. In this paper, it shows the preprocessing with box filtering and also guided filtering for preserving the edges of the input image using a guidance image that is an input image itself.
