1. A method, comprising: determining an estimate of light that is contributed by haze in digital images that include one or more objects at least partially obscured by the haze that is visible in the digital images; clearing the haze from the digital images based on the estimate of the light that is contributed by the haze to generate clearer digital images; computing an optical flow between the clearer digital images; and refining the clearer digital images based on the optical flow to further clear the haze from the clearer digital images.
