METHOD FOR COLOR BALANCING UNDERWATER PHOTOGRAPHY

摘要

A system and method that receives and edits image data of an underwater scene in a digital image in order to remove undesirable tints from objects in the scene. In some embodiments, colors near the color of the water itself are protected to leave the water looking blue. Removing undesirable tints without removing the tint of the water itself results in images with more realistic coloring of people and objects in the scene, without eliminating the color cues (e.g., blue water) that indicate that the image is a photograph of an underwater scene.

主权项

1. A method of adjusting colors of a digital image, the method comprising:
calculating, using a computing device, for each pixel of a set of pixels of the digital image, a first distance in a color space from a first color to a color of the pixel; calculating, using the computing device, for each pixel of the set of pixels of the digital image a second distance in the color space from a second color to the color of the pixel; based on the first and second distances, calculating, using the computing device, a strength value for each pixel; and adjusting, using the computing device, the color of each pixel of the set of pixels, wherein the adjustment is based on the strength value and the first color, to generate an adjusted digital image.
