4.1. Diffusion Models as Generative Denoiser Prior 扩散模型作为生成式去噪先验的一个重要特性是,模型可以被理解为生成器(前几步)和去噪器(剩余步骤)的组合。直觉上,我们可以将扩散模型作为即插即用IR中HQS算法的深度先验去噪器,并使用合适的初始化。 z_k \approx x_k + \frac{1-\bar{\alpha}_t}{\bar{...
1. 解决的问题 本文引入了一种准确的反转技术,从而促进了基于文本的直观修改本文提议的反演过程由两个关键的新组合组成:(i)扩散模型的关键反转,目前的方法旨在将随机噪声样本映射到单个输入图像,但本文为每…
Diffusion Models (DMs) have evolved into advanced image generation tools, especially for few-shot generation where a pretrained model is fine-tuned on a small set of images to capture a specific style or object. Despite their success, concerns exist about potential copyright violations stemming from...

Null-text Inversion技术与Guided Diffusion Models的结合主要体现在对空文本嵌入的优化上。以下是实现这一结合的关键步骤: 初始化:给定一张真实图像和相应的文本提示,使用DDIM反转技术将图像映射到模型的潜在空间中。 空文本嵌入优化:在Classifier-free Guidance的框架下,优化空文本嵌入以更好地重建原始图像。这一步通过...
of images. To edit a real image using diffusion models, one must first invert the image to a noisy latent from which an edited image is sampled with a target text prompt. However, most methods lack one of the following: user-friendliness (e.g., additional masks or precise descriptions of...
Inversion-Based Style Transfer with Diffusion Models The artistic style within a painting is the means of expression, which includes not only the painting material, colors, and brushstrokes, but also the high-level attributes including semantic elements, object shapes, etc. Previous arbitrary example...

本项目旨在Windows 10 上实现InST的部署工作。原版是Jupyter Notebook的。 其实很简单,可以直接下载我做好了的程序,接下来您自己下一下预训练模型放入Models文件中就行了。 下载链接:CSDN Github 接下来讲讲和源代码具体的区别: 1.每次只能运行单张图像,输出也是 2.每次运行时,记得删除Output里的原始图像 文件...
