Abstract
A system and method for single-image dehazing of natural images are provided herein. Embodiments of the method may include the following steps: dividing a natural image which include haze, into a plurality of image patches, wherein the image patches are sufficiently small so that pixels of the image patches exhibit one dimensional distributions in RGB color space, denoted color-lines; generating local image formation models for the pixels of the plurality of image patches, respectively, based on a relationship between the color-lines and the haze; calculating an offset of the color-lines from origin point of the respective local image formation models, for the image patches; and estimating scene transmission of the natural image, based on the calculated offsets.
