Single Image Dehazing using Saliency Map

Abstract

Recently, research of dehazing for improving the visibility of images has been conducted widely. There is a method based on Dark Channel Prior as removing haze from single image, and it is simple and is used widely. However, there is a problem that white objects and illuminations are wrongly recognized as atmosphere light. Therefore, in this research, we propose a method using Saliency Map in estimating atmosphere light. In our method, we prevent from estimating atmosphere light from white objects and illuminations because we estimate it from regions with low saliency. As a result, we create clearer image than previous method, and we show that proposed method is effective.
