• Abstract summary: We propose a method to estimate 3D human poses from substantially blurred images. Key idea is to tackle the inverse problem of image deblurring by modeling the forward problem with a 3D human model, a texture map, and a sequence of poses to describe human motion. Using a differentiable step, we can solve the inverse problem by backpropagating the pixel-wise reprojection error to recover the best human motion representation.

• Abstract: We propose a method to estimate 3D human poses from substantially blurred images. The key idea is to tackle the inverse problem of image deblurring by modeling the forward problem with a 3D human model, a texture map, and a sequence of poses to describe human motion. The blurring process is then modeled by a temporal image aggregation step. Using a differentiable renderer, we can solve the inverse problem by backpropagating the pixel-wise reprojection error to recover the best human motion representation that explains a single or multiple input images. Since the image reconstruction loss alone is insufficient, we present additional regularization terms. To the best of our knowledge, we present the first method to tackle this problem. Our method consistently outperforms other methods on significantly blurry inputs since they lack one or multiple key functionalities that our method unifies, i.e. image deblurring with sub-frame accuracy and explicit 3D modeling of non-rigid human motion.

  We propose a robust method for 3D reconstruction of inconsistent images, enabling real-time rendering during inference. We recast the reconstruction problem as a 4D task and introduce an efficient 3D modeling approach using 4D Gaussian Splatting. Experiments demonstrate that our method achieves photorealistic, real-time animation of 3D human avatars from in-the-wild images.

  We present DreamDance, a novel method for animating human images using only skeleton pose sequences as conditional inputs. Our key insight is that human images naturally exhibit multiple levels of correlation.

  regression-based methods have dominated the field of 3D human pose and shape estimation. We propose to construct dense correspondences between initial human model estimates and the corresponding images. We show that our approach not only consistently leads to better image-model alignment, but also to improved 3D accuracy.

  We present Score-Guided Human Mesh Recovery (ScoreHMR), an approach for solving inverse problems for 3D human pose and shape reconstruction. ScoreHMR mimics model fitting approaches, but alignment with the image observation is achieved through score guidance in the latent space of a diffusion model. We evaluate our approach on three settings/applications: (i) single-frame model fitting; (ii) reconstruction from multiple uncalibrated views; (iii) reconstructing humans in video sequences.

  We present a diffusion model-based framework for animating people from a single image for a given target 3D motion sequence. For the first part, we learn an in-filling diffusion model to hallucinate unseen parts of a person given a single image. Second, we develop a diffusion-based rendering pipeline, which is controlled by 3D human poses.

  SiTH is a novel pipeline that integrates an image-conditioned diffusion model into a 3D mesh reconstruction workflow. We employ a powerful generative diffusion model to hallucinate unseen back-view appearance based on the input images. For the latter, we leverage skinned body meshes as guidance to recover full-body texture meshes from the input and back-view images.

  We address the novel task of jointly reconstructing the 3D shape, texture, and motion of an object from a single motion-blurred image. While previous approaches address the deblurring problem only in the 2D image domain, our proposed rigorous modeling of all object properties in the 3D domain enables the correct description of arbitrary object motion.

  In this work, we address the problem of multi-person 3D pose estimation from a single image. A typical regression approach in the top-down setting of this problem would first detect all humans and then reconstruct each one of them independently. Our goal is to train a single network that learns to avoid these problems and generate a coherent 3D reconstruction of all the humans in the scene.
