During the training stage, the gradient of the conditional distribution is approximated by using a conditional diffusion model to predict the noise added to the original urban morphology. In the generation stage, the corresponding conditional distribution is parameterized based on the noise predict...
The pose image of the model, after encoding through a pose encoder, also enters the diffusion U-Net to guide the generation process of the cloth. 我们针对虚拟试衣任务改进了条件扩散模型,采用服饰平铺图、模特图、模特姿态图作为扩散模型的条件输入。服饰图作为reference unet和DINO-2的输入,用于编码服饰...
Autoregressive Model的目的是将原始的caption条件,离散化成更加丰富的条件。在训练阶段是和Diffusion一起优化的。Text Encoder的输出以cross attention的形式作用在Autoregressive Model上,迭代预测下一个token。最终训练好Autoregressive Model后,将Autoregressive Model最后一层的embedding和Text Encoder的concat在一起作为条件输...

We map observational and ESM data to a shared embedding space, where both are unbiased towards each other and train a conditional diffusion model to reverse the mapping. Our method can be used to correct any ESM field, as the training is independent of the ESM. Our approach ensures ...
This paper propose the Patch-based Simplified Conditional Diffusion Model (PSC Diffusion) for low-light image enhancement due to the outstanding performance of diffusion models in image generation. Specifically, recognizing the potential issue of gradient vanishing in extremely low-light images due to ...
