Online Video Stream Stylization

چکیده
1 This paper gives an automatic method for online video stream styl2 ization, producing a temporally coherent output video stream. Our 3 system transforms video into an abstract style with large regions of 4 constant color and highlighted bold edges. Our system includes two 5 novel components. Firstly, to provide coherent and simplified out6 put, we segment frames, and use optical flow to propagate segmen7 tation information from frame to frame; an error control strategy 8 is used to help ensure that the propagated information is reliable. 9 Secondly, to achieve coherent and attractive coloring of the output, 10 we use a color scheme replacement algorithm specifically designed 11 for an online video stream. We demonstrate real-time performance, 12 allowing our approach to be used for live communication, video 13 games, and related applications. 14

Real-time Cartoon-like Stylization of AR Video Streams on the GPU
The ultimate goal of many applications of augmented reality is to immerse the user into the augmented scene, which is enriched with virtual models. In order to achieve this immersion, it is necessary to create the visual impression that the graphical objects are a natural part of the user’s environment. Producing this effect with conventional computer graphics algorithms is a complex task. Vari...
متن کاملTemporal coherent image segmentation and its applications
We propose a trapped-ball method for image segmentation, which is fast, supports non-uniformly colored regions, and allows robust region segmentation even in the presence of imperfectly linked region edges. We also introduce two applications by using the trapped-ball image segmentation, for temporal coherent animations generation and editing. First, we present a system for vectorizing 2D raster...
متن کاملReality Tooning: Fast Non-Photorealism for Augmented Video Streams
Recently, we have proposed a novel approach to generating augmented video streams. The output images are a non-photorealistic reproduction of the augmented environment. Special stylization methods are applied to both the background camera image and the virtual objects. This way, the graphical foreground and the real background images are rendered in a similar style, so that they are less distin...
متن کاملVideo Texture Synthesis Based on Flow-Like Stylization Painting
The paper presents an NP-video rendering system based on natural phenomena. It provides a simple nonphotorealistic video synthesis system in which user can obtain a flow-like stylization painting and infinite video scene. Firstly, based on anisotropic Kuwahara filtering in conjunction with line integral convolution, the phenomena video scene can be rendered to flow-like stylization painting. Se...
متن کاملVideo Painting based on a Stabilized 3D Flow Field
We present a method for generating a 3D feature flow field from a video and its application to video stylization. Our method extracts smoothly aligned 3D vectors that describe the smallest variation of colors in both spatial and temporal dimensions of the video, and thus efficiently preserves both spatial and temporal coherence in a relatively inexpensive manner. We use this flow field forms th...
