初始帧经过Frame Interpolation这一module,会进步增加视频帧的数量 之后经过Spatiotemporal Super-Resolution,将会提高视频帧的分辨率 最后,经过最后一个Spatial Super Resolution进一步提高生成视频的质量。 接下来是Make-A-Video的模型细节: 图1 图2 值得注意的是,即使在视频生成过程中,2D上所有的操作基本都是从预训练的...

整个模型包含一个latent video diffusion model,两个video super resolution diffusion model,最终生成512x896的8 fps的视频。 模型的部分网络架构如下图所示,首先用MAGVIT v2(关于MAGVIT v2,可以看我的另外一篇解读)对图像/视频进行编码,这里没有采用MAGVIT v2的量化方案对token进行量化,用的是量化前的token,因为...
而常见的diffusion model，他们会用这个 diffusion objective 自己去学一个 super resolution，至少到目前为止，这条 super resolution 上的技术路线，大家还是没有很大程度的共享的，我觉得以后可能可以。不过这里面其实有一个问题，就是 super resolution，目前当然大家都 teacher forcing ，就是我用原始的低分辨率视频和...
Real-world low-resolution (LR) videos have diverse and complex degradations, imposing great challenges on video super-resolution (VSR) algorithms to reproduce their high-resolution (HR) counterparts with high quality. Recently, the diffusion models have shown compelling performance in generating ...

Diffusion models are just at a tipping point for image super-resolution task. Nevertheless, it is not trivial to capitalize on diffusion models for video super-resolution which necessitates not only the preservation of visual appearance from low-resolution to high-resolution videos, but also the te...
当然在现阶段,因为视频是一个这个维度比较高的领域,那么它对效率的要求也更高一些,可能还是需要仍然使用 super resolution 一段时间,然后架构上是否通用,目前我们用的架构在里面其实是一个 mask 的 transformer。然后做 super resolution,因为它会更快一些。它又不是 Diffusion, 它比 Diffusion 更快一些。而常见的...
