最后,你可能听说过 k-diffusion 并好奇这是什么东西。它其实就是指 Katherine Crowson 的 GitHub 仓库:k-diffusion,该仓库实现了 Karras 论文中提到的诸多采样器。 实际上,SD webui 中除了 DDIM、PLMS 和 UniPC 外的其他所有采样器都是使用的 k-diffusion 仓库的实现。 评估采样器 如何选择采样器?本节将会进行...
首先,对于Stable Diffusion有多种不同的应用场景,比如文生图、图生图、图像重绘等,不同的应用场景在模型的处理细节上会有些许差异,但整体逻辑基本相似。 另外,截止至今 Stable Diffusion 已经迭代更新了多个版本,Stable Diffusion V1(1.1-1.5) 、SD V2(2.0-2.1) 、SDXL以及最近更新的SD3模型,不同版本之间模型结构和...
support for stable-diffusion-2-1-unclip checkpoints that are used for generating image variations. It works in the same way as the current support for the SD2.0 depth model, in that you run it from the img2img tab, it extracts information from the input image (in this case, CLIP or ...

e.g., diffusion into aquifers in overlying sediments. The fluids diffused within the sediments provide reduced chemical species and other nutrients to subsurface microbes. Some of the microbes may be grazed upon, thereby supporting benthic animals, and the others may generate reduced chemical species...
Stable Diffusion模型通过一种称为“去噪”的过程来生成图像,这个过程涉及到在潜在空间中逐步从随机噪声中提取出有意义的图像特征。 模型首先在潜在空间中生成一个完全随机的噪声图像。这个图像是随机的,不包含任何有意义的信息。 噪声预测器(也称为去噪函数)估计这个随机图像中的噪声。这个预测器是模型的一部分,它学习...
