Their method can merge an arbitrary length video based on natural scene. Their method first analyzed the motion of texture particles and segmented frames into patches, then they reorganized the patches to reduce error dither. put forward an editing nature phenomena method to generate the final video texture. To ensure continuity, the input frames were divided into some parts, and then they would be synthesized to video texture. Based on image cutting and synthesizing technique, Kuwahara improved video texture synthesis method. The proposed method has realized highly third dimension scenery animation successfully. They used L2 distance to measure similarity between neighbor frames and maintained playing continuity among video frames. Schödl and Essa also employed video texture technique to animation. Generally, video texture may be regarded as expansion of image not only in the time domain but also in natural phenomena simulation. Because of its wide application in the entertainment and industry and so forth, computer-based phenomena video texture becomes hot topic.
So, video texture is the best media to represent natural phenomena of our nature. Then video texture works well for motions not only repetitive but also quasi-repetitive, such as swaying trees, waterfalls, and flickering flames. The natural short video can be captured to synthesize infinite scene based on the technique of video texture synthesis. This medium provides a continuous, infinitely varying stream of video images, and it can show an arbitrary length of video. Video texture has qualities between photograph and video.
In order to solve the above problems, Schödl and Essa proposed a new type of medium called “video texture”.
In addition, it needs too much storage space. Further, though video captures the time-varying behavior of the phenomenon, it lacks the “timeless” quality of the photograph or image. Therefore, video needs a beginning, a processing, and the ending frame. On the other hand, though video is considered as the best media to show natural scene, it also has some shortcomings, such as if video scene should be stored on a computer or other storage devices, we always apply finite duration video clip. However, both natural and artificial phenomena cannot adequately be captured by a single static photo or image. Most natural phenomena can use image or video to demonstrate directly.
