| The processing of video artistic style, as a major research of a non-photorealistic rendering, has a great prospect and a very extensive study of research content. In recent years, Researching content of the artistic drawing of video and images include: 1. To improve the artistic effect of video and images. 2. To improve the real-timing in video processing 3. Reduce the algorithm complexity and so on.The dissertation had accomplished a system of video artistic style, which is to reduce the artists complex and heavy workload in the artistic painting filed, and its practical significance is more obvious. The system has been done in a personal PC and the video artistic process makes use of DirectShow to process, which has a great advantage to deal with streaming media and it combined with digital image processing methods to achieve artistic effects together. The main advantage of the algorithm is simple and feasible, artistic effects and real-timing can satisfy the requirements. In the video processing, my works include: extraction of video frames, noise smoothing of the frame image, the outline of image enhancement by edge detection, making use of regional color uniformity processing and filling to achieve cartoon effect, making use of convolution operation is complete relief, pencil and so on, with the pointer and image storage information to achieve the effect of mosaic, using the texture in DirectX to achieve the 3D display of the frames. In the image cartoon processing, the thesis mainly achieve its cartoon effect by way of a series of processes which included image feature space conversion, bilinear filtering, edge detection, image pseudo-quantitative processing and image edge distortion and so on. Finally the dissertation has integrated of the image cartoon and video artistic processing to realize a video-playing, camera capturing, a processing system of video artistic style, and accomplished the design of the overall framework, algorithm design and code realization. |
