Simple and Effective Method to Remove Hazy Effect from Underwater Images
Abstract
Underwater images usually suffer by the underwater hazy effect and color degra-dation caused by suspended particles such as minerals, sand and dust particles in the water. To recover underwater scene with actual colors, fine details and without hazy effect is a challenging task. In this work, we are presenting an easy and effective approach to haze effect removal from single underwater hazy images. The proposed approach comprises of three steps. Initially, color bal-ancing is used on underwater images to retrieve the actual color of underwater objects. Next step deal with the removal of the underwater hazy effect by using modified dark channel prior. Finally, local detail enhancement of the haze-free image is achieved by using discrete cosine transform (DCT). The effectiveness of the proposed work has been proven by comparing our results with some state-of-the-art-methods.
