Optical Flow Accounting for Image Haze

摘要

In embodiments of optical flow accounting for image haze, digital images may include objects that are at least partially obscured by a haze that is visible in the digital images, and an estimate of light that is contributed by the haze in the digital images can be determined The haze can be cleared from the digital images based on the estimate of the light that is contributed by the haze, and clearer digital images can be generated. An optical flow between the clearer digital images can then be computed, and the clearer digital images refined based on the optical flow to further clear the haze from the images in an iterative process to improve visibility of the objects in the digital images.

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.
