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,模型需要具备有处理时间和空间维度信息以及时间-空间跨域的信息融合能力 当前图像生成的diffusion

We compare this approach against six baselines on four datasets involving natural and simulation-based videos. We find significant improvements in terms of perceptual quality and probabilistic frame forecasting ability for all datasets.doi:10.3390/e25101469Ruihan Yang...

Instruction-Based Editing 数据 “数据”角度主要还是关注生成图像的一些特性,比如说生成图像的resolution、domain等等。 生成图像分辨率 关注生成图像的“分辨率”其实就是做“High-Resolution Image Synthesis”,个人一直认为属于是“简单但难解的工程问题”,原因很简单,分辨率成倍增大,生成模型要生成的像素点就需要以2次...
1. Video Compression: Video compression plays a crucial role in stable video diffusion. To reduce the size of video data for transmission and storage, compression algorithms are employed. These algorithms eliminate redundant and irrelevant information, using various techniques such as frame difference, ...
The denoising diffusion model is based on the three-dimensional U-Net video architecture33, which iteratively adds information to a Gaussian prior. To include a temporal dimension, each spatial convolution and attention layer is followed by temporal attention computed over the 11 strain steps. We co...
