Brownian Bridge Diffusion Model (BBDM) VQGAN(Vector Quantized Generative Adversarial Network)是一种生成对抗网络(GAN)架构,用于生成高质量的图像。VQGAN 的设计结合了向量量化和生成对抗网络的概念,以产生具有视觉真实感和多样性的图像。 以下是对VQGAN的详细解释: 生成对抗网络(GAN): GAN 是一种深度学习模型,...
摘要 常见的图像到图像的翻译方法依赖于从源域和目标域的数据上进行联合训练。训练过程需要同时访问两个数据集,这阻碍了数据分离和隐私保护;现有模型不能轻易地适应新域对的翻译。我们提出了双重扩散隐式桥接(DDIBs),一种绕过域对训练的方法。图像翻译通过DDIBs依赖于分别在每个域上独立训练的两个扩散模型,并且是一...

对于两个不同的文本嵌入 Vsrc 和 Vref,他们分别产生两种不同的噪声预测 ϵsrc=ϵθ(zt,t,vsrc)和 ϵref=ϵθ(zt,t,vref)。 根据分类器引导和无分类器引导的结论,每个扩散步骤中的噪声预测可以看作是为分数估计函数ϵθ(zt,t,vsrc)≈−σt∇ztlogp(zt|v) 独立的文本嵌入Vsrc和Vref可以在ϵ...

However, the complexity of training GANs and the computational expense associated with diffusion models hinder their development and application in this task. To address these issues, we introduce a Cross-conditioned Diffusion Model (CDM) for medical image-to-image translation. The core idea of CDM...
We introduce Palette, a simple and general framework for image-to-image translation using conditional diffusion models. On four challenging image-to-image translation tasks (colorization, inpainting, uncropping, and JPEG decompression), Palette outperforms strong GAN and regression baselines, and establis...
Meanwhile, diffusion models (DMs) provide an alternative route to image generation [19]. 这段文字是介绍一种用于图像生成的方法,叫做扩散模型(Diffusion models)。扩散模型的基本思想是将图像生成的过程分解为一系列的去噪自编码器(denoising autoencoders),每个去噪自编码器都可以将图像从一个更加模糊和噪声的状...
