Adaptive color image style transformation for video

摘要

This paper presents a simple and fast color style transfer algorithm for video. Based on this proposed algorithm, users can simply select two reference images during the video conversion to complete the color transfer process. Generally speaking, video is a compilation of related images, thus we first split the video into an image sequence, and then perform one-by-one color transfer for each video frame. In order to speed up the color characteristic parameters processing of the reference image and target video, the algorithm exploits the lαβ color space for transfer, since it has a lower color channel correlation. The resulting video transfer produces a digital special effects scene with two color-style transformed reference images. Lastly, the produced results are analyzed. The changes in each frame are minute, and are analyzed by the human eye for its video structure. The assessment illustrates good visual effects are achieved, suggesting this technique may be applied to special effects generation in videos.
