个人理解:diffusion model的reverse process每一步扩散都是在一个正态分布的mean附近采样,而CLIP guidance在这个mean附近增加一个扰动,该扰动与 f(x)和g(c)点积的梯度 有关。 直观的motivation:一些利用CLIP将文本特征融合到diffusion model中的方法,通常是对diffusion model reverse process过程中加过噪声的图像进行特...
更大的模型:算法采用了Guided Diffusion方法中相同的Autoencoder结构,但是进一步扩大了通道数量,使得最终的网络参数数量达到了3.5 billion 文章: GLIDE: Towards Photorealistic Image Generation and Editing with Text-Guided Diffusion Models Denoising Diffusion Probabilistic Models Improved denoising diffusion probabilistic ...
D4: Text-guided diffusion model-based domain adaptive data augmentation for vineyard shoot detectionIn an agricultural field, plant phenotyping using object detection models is gaining attention. However, collecting the training data necessary to create generic and high-precision models is extremely ...
Diffusion models have recently gained significant traction due to their ability to generate high-fidelity and diverse images and videos conditioned on text prompts. In medicine, this application promises to address the critical challenge of data scarcity, a consequence of barriers in data sharing, stri...
To fully leverage the image synthesis performance of diffusion models with the purpose of image manipulation, we require the deterministic process both in the forward and reverse direction with pretrained diffusion models for successful image manipulation. On the other hand, for the image translation ...
In recent years, denoising diffusion models have achieved remarkable success in generating pixel-level representations with semantic values for image generation modeling. In this study, we propose a novel end-to-end framework, called TGEDiff, focusing on medical image segmentation. TGEDiff fuses a te...
