摘要 与生成对抗网络(GAN)相比,去噪扩散概率模型(DDPM)在各种图像生成的任务中都取得了显著的成功。最近,关于语义图像合成(semantic image synthesis)的工作实际上还是主要遵循GAN的方法,这可能导致生成图像的质量或者多样性并不令人满意。在本文中,我们提出了一种基于DDPM的语义图像合成新框架。之前的条件扩散模型直接将...
1. Introduction 本文的主要贡献: 1. 本文基于DDPM,提出了一种新的用于生成高保真度和多样性的语义图像的Diffusion模型,称作Semantic Diffusion Model(SDM)。 2. 现有的条件Diffusion模型不能很好的处理带噪声的输入和语义的mask。本文提出了一种新的网络架构,能够同时很好的处理带噪声的输入和语义mask。 3. 为了在采...
Semantic Image Synthesis via Diffusion Models (SDM) Paper Weilun Wang,Jianmin Bao,Wengang Zhou,Dongdong Chen,Dong Chen,Lu Yuan,Houqiang Li, Abstract We provide our PyTorch implementation of Semantic Image Synthesis via Diffusion Models (SDM). In this paper, we propose a novel framework based ...
To enhance the generation quality and semantic alignment in semantic image synthesis, we have reengineered the noise mapping and semantic space embedding, proposing a novel semantic image synthesis model, GAN-Diffusion Relay Model (GDRM), based on GAN and relay diffusion model. Extensive experiments ...
Controllable image synthesis models allow creation of diverse images based on text instructions or guidance from an example image. Recently, denoising diffusion probabilistic models have been shown to generate more realistic imagery than prior methods, and have been successfully demonstrated in unconditional...

Text-to-image diffusion models have made significant advances in generating and editing high-quality images. As a result, numerous approaches have explored the ability of diffusion model features to understand and process single images for downstream tasks, e.g., classification, semantic segmentation,...
