Abstract
A method for removing haze from an image is provided. The image is converted to S(x) and V(x), the S(X) is saturation component of the image, and the V(x) is value component of the image. The S(x) is filtered to obtain S'(x), and the V(x) is filtered to obtain V′(x). A depth d(x) is estimated by calculating a difference between the S′(x) and V′(x). Once a transmission map t(x) is calculated based on the d(x), haze is removed from the image based on the transmission map t(x).
