A color video always conveys more vivid sentiments than a grayscale one. Obtaining a grayscale video from a color video is almost trivial but the converse is known to be hard. Nowadays, digital camcorders come equipped with an infrared device for night shot that enables one to shoot home videos in the dark. Unfortunately, the infrared lighting device used generates a "green-scale" video which is akin to a grayscale video albeit possessing all tints of green. In this paper, we present a novel technique for colorizing infrared home videos. We first convert the green scale video into grayscale, afterwards our technique involves generating key-frames for every shot and then building up a one to one correspondence map between the key frames and the designated color images. These pairs are used to generate the color palette table for the video segment, which is then utilized to colorize that segment of the home video. Our novel technique could also be applied for colorizing X-ray videos generated by diagnostic imaging devices as well as surveillance videos generated by baggage scanners at airports.
