然后采用1/\hat \sigma的系数来rescale latent,这样就尽量保证latent的标准差接近1(防止扩散过程的SNR较高,影响生成效果,具体见latent diffusion论文的D1部分讨论),然后扩散模型也是应用在rescaling的latent上,在解码时只需要将生成的latent

Stable Diffusion的核心来源于Latent Diffusion这个工作,常规的扩散模型是基于Pixel(像素)的生成模型,而Latent Diffusion是基于Latent的生成模型,它先采用一个autoencoder将图像压缩到Latent空间,然后用扩散模型来生成图像的Latents,最后送入autoencoder的decoder模块就可以得到生成的图像。 Stable Diffusion模型的主体结构如下图...
Stable Diffusion 模型,已经成为 AI 行业从传统深度学习时代走向 AIGC 时代的标志性里程碑。越来越多的开发者借助 stable-diffusion-webui (以下简称 SDWebUI) 能力进行 AI 绘画领域创业或者业务上新,获得高流量及商业价值,但是面对多客户、高并发的复杂场景,使用原生 Stable Diffusion API 会面临以下挑战: 显卡资源...

If you run into a problem with Automatic1111’s Stable Diffusion Web UI(webui) with this error “AssertionError: Could Not Find Upscaler named []”, you can try this fix. I updated my webui directory very often and run into a lot of problems every time I updated it. The ...
StableSR for Stable Diffusion WebUI - Ultra High-quality Image Upscaler - clayne/sd-webui-stablesr
大家好,我是Stable Diffusion中文网的小编。今天我们来聊聊Upscaler,这是一种图像高清修复算法处理的技术。Upscaler是图像处理中非常重要的一个环节,它可以帮助我们将低分辨率的图像提升到高分辨率,从而获得更加清晰、细腻的图像。传统的Upscaler大多是基于算法的,它们通过对图像进行各种运算来提升分辨率,但往往会导致...
AI Image upscalers like ESRGAN are indispensable tools to improve the quality of AI images generated by Stable Diffusion. It is so commonly used that many Stable Diffusion GUIs have built-in support. Here, we will learn what image upscalers are, how they work, and how to use them. ...
