Abstract

A novel over exposure (OE) correction method using Dark Channel Prior and image fusion technique is proposed in this work. Assuming an OE image can be modeled as a normal exposure image added up with a layer of asymmetrical haze, its submerged information in OE regions is enhanced by haze removal model. With image fusion technique, the obtained texture in OE regions is used to restore the over exposure. Experiments show that our method works well in submerged information restoration without increasing pseudo-information and over Saturation.
