二、 Diffusion for Video Generation Diffusion模型在Image Generation上的成功也促使其被应用于Video Generation上。近年来,一些工作试图使用现有的Image Diffusion模型生成视频。具有代表性的工作是Text2Video-Zero。该工作试图直接使用已训练好的Image Diffusion模型生成视频,无需额外的训练过程。
关于diffusion-based Video Generation的一些随想视频生成相对图像生成,主要的挑战: 在空间维度的基础上,增加了时间维度(temporal dimension)上不同时间帧(frames)需要保证连贯性和一致性的需求。因此,模…
Sora的亮相带火了两个东西——一个是Diffusion Transformer，另一个则是text-to-video generation这件事。
We propose an autoregressive, end-to-end optimized video diffusion model inspired by recent advances in neural video compression. The model successively generates future frames by correcting a deterministic next-frame prediction using a stochastic residual generated by an inverse diffusion process. We ...

Generating temporally coherent high fidelity video is an important milestone in generative modeling research. We make progress towards this milestone by proposing a diffusion model for video generation that shows very promising initial results. Our model is a natural extension of the standard image ...
diffusion models; deep generative models; video generation; autoregressive models1. Introduction The ability to anticipate future frames of a video is intuitive for humans but challenging for a computer [1]. Applications of such video prediction tasks include anticipating events [2], model-based ...
