Depth-Aware Video Abstraction

In this paper, we present a novel depth-aware abstraction approach for videos. By introducing the additional depth cues, our approach is able to enhance the depth perception of the artistic-abstraction video. We first recover consistent depth information from the input video using multiview stereo and energy optimization algorithm. Then, the coherent line is extracted by employing the an isotropic difference-of-Gaussians filter, and the Gaussian Kuwahara filter is further employed to produce the effect of artistic-abstraction. Finally, the depth aware video artistic-abstraction is achieved by unsharp masking the consistent video depth. Our algorithm is effective for artistically representing the depth perception of artistic abstraction video. Experimental results on a variety of videos show that the proposed approach successfully produces a visually satisfying depth perception for the artistic-abstraction video.
