论文摘要
该项目实施了Szeliski的论文“视频纹理”。目的是创建一个“运动图片”，或者正如我们所称其为GIF一样；这是“照片和视频之间的某个地方”。这个想法是输入一个具有重复运动（纹理）的视频，例如旗帜挥舞，雨或蜡烛火焰。输出是一个新视频，它以无缝的方式无限地扩展了原始视频。实际上，输出并不是真正的信息，而是使用视频播放器进行循环，并且似乎永远不会重复。 我们实现的目标是：通过从粗略的距离切换到最复杂的小波距离来提高距离度量；在建议的基本算法中增加强度归一化，交叉效果和变形。我们还实验了多样性与光滑之间的权衡。
This project implements the paper "Video Textures" by Szeliski. The aim is to create a "Moving Picture" or as we popularly call it, a GIF; which is "somewhere between a photograph and a video". The idea is to input a video which has some repeated motion (the texture), such as a flag waving, rain, or a candle flame. The output is a new video that infinitely extends the original video in a seamless way. In practice, the output isn't really infinte, but is instead looped using a video player and is sufficiently long as to appear to never repeat. Our goal from this implementation was to: improve distance metric by switching from a crude sum of squared distance to most sophisticated wavelet-based distance; add intensity normalization, cross-fading and morphing to the suggested basic algorithm. We also experiment on the trade-off between variety and smoothness.
