Model overview
ScaleCrafter is a powerful AI model capable of generating high-resolution images and videos without any additional training or optimization. Developed by a team of researchers, this model builds upon pre-trained diffusion models to produce stunning results at resolutions up to 4096x4096 for images and 2048x1152 for videos.
The ScaleCrafter model addresses several key challenges in high-resolution generation, such as object repetition and unreasonable object structures, which have plagued previous approaches. By examining the structural components of the U-Net in diffusion models, the researchers identified the limited perception field of convolutional kernels as a crucial factor. To overcome this, they propose a simple yet effective re-dilation technique that dynamically adjusts the convolutional perception field during inference.
The model's capabilities are showcased through impressive examples, including a "beautiful girl on a boat" at 2048x1152 resolution and a "miniature house with plants" at a staggering 4096x4096 resolution. The researchers also demonstrate the model's ability to generate arbitrary higher-resolution images based on Stable Diffusion 2.1.
ScaleCrafter shares similarities with other models developed by the same maintainer, cjwbw, such as [object Object], [object Object], [object Object], and [object Object]. These models also focus on scaling up image and video generation capabilities.
