采用了一种混合使用卷积和 Transformer 的架构,不知道有什么好处。 Gen-1 (Runway) 我看这张图里,值得一提的是用MIDaS来估单目深度。MIDaS 本身很强大,提供的深度信息能很大程度上帮助其他模块获得帧间的对应关系。 Video LDM Stable Video Diffusion SD 会搞数据集说明专业。
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。 图七Text2Video-Zero 具体来说,Text2Video-Zero先仅生成第一...

However, the development of Text-2-Video models poses a more formidable challenge. The goal is to achieve coherence and consistency across each generated frame and maintain generation context from the video's inception to its conclusion. Yet, recent advancements in Diffusion-based models offer promis...
SenseAI:基于LLM的视频生成模型会不会在长期比Diffusion 类型的模型更具潜力和优势?LLM的架构和 Diffusion 架构图片和视频生成,未来是否会到一个趋势,就是各自生成的质量都非常接近,但是 LLM 架构在视频内容和逻辑上会更突出。还是会有别的趋势? 于博士:这是一个很好的问题,刚才问题当中所抛出的这些观点,我大体上...
