2.1 Image-to-Image Diffusion Models with pose conditioning 此公式是Diffusion Model的原始表达。 在给定初始的高斯噪声,和xk处的噪声,求得图像的b分布。 A diffusion model has latent variablesz={zt|t∈[0,1]}and is specified by a noise schedule comprising differentiable functions αt, σt such that...
# Novel View Synthesis with Diffusion Models 1. Introduction 本文利用diffusion模型,在给定参考图的条件下,生成指定pose的图像,作者称为3DiM。并且可以在给定一张特定视角的图的条件下,生成其他所有视角的图。 本文的主要贡献: 1. 提出了3DiM模型,利用diffusion实现novel view synthesis。 2. 提出了stochastic ...
3D-free meets 3D priors: Novel View Synthesis from a Single Image with Pretrained Diffusion Guidance 来自 arXiv.org 喜欢 0 阅读量: 4 作者:T Kang,D Kothandaraman,D Manocha,MC Lin 摘要: Recent 3D novel view synthesis (NVS) methods are limited to single-object-centric scenes and struggle ...
We propose Latent Diffusion-Enhanced 3D Gaussian Splatting (LatentDiff-3DGS) model, an extension of 3D Gaussian Splatting (3DGS) that incorporates pretrained latent diffusion models to enhance the visual quality of novel view synthesis. By integrating a large-scale latent diffusion model into the ...

The hydroxyl radical is the most toxic; it has limited diffusion, but can react with other molecules and inactivate them. O2− and hydrogen peroxide are less toxic but are implicated in the Fenton reaction (Fe++ + H2O2 → Fe+++ + OH + OH−) that by producing the hydroxyl ...
the rate-controlling step is intraparticle diffusion. When the plots do not pass through the origin, it indicates that the intraparticle diffusion is not the only rate-limiting step, but that other kinetic models may also control the rate of adsorption, all of which may be operating concurrentl...
通过实验,作者们证明了在2D图像扩散模型中,如Stable Diffusion模型,确实编码了3D知识,并且展示了这种结构可以被利用于3D视觉任务。 在这项研究中,作者们提出了一种名为Viewpoint Neural Textual Inversion (ViewNeTI) 的方法,该方法能控制从冻结的扩散模型生成的图像中对象的3D视点。他们训练了一个小型神经映射器...
潜在视频扩散模型:SV3D利用了一种称为潜在视频扩散模型(例如Stable Video Diffusion - SVD)的技术,这种模型能够生成具有高度一致性的多视角视频。通过这种方式,SV3D可以从单个图像生成一系列新的视角图像,这些图像在视觉上与原始图像保持一致,同时展现了对象的不同视角。
