GFPose: Learning 3D Human Pose Prior with Gradient Fields
Download Abstract: Learning 3D human pose prior is essential to human centered AI. Here, we present GFPose, a versatile frame work to model plausible 3D human poses for various appli cations. At the core of GFPose is a time-dependent score network, which estimates the gradient on each body joint and progressively denoises the perturbed 3D …

Diffusion-based Generation, Optimization, and Planning in 3D Scenes
Download Abstract: We introduce SceneDiffuser, a conditional generative model for 3D scene understanding. SceneDiffuser provides a unified model for solving scene-conditioned generation, optimization, and planning. In contrast to prior works, SceneDiffuser is intrinsically scene-aware, physics-based, and goal-oriented. With an iterative sampling strategy, SceneDiffuser jointly formulates the scene-aware generation, physics-based optimization, and goal-oriented planning via a …

Detecting Human-Object Contact in Images
Download Abstract: Humans constantly contact objects to move and perform tasks. Thus, detecting human-object contact is important for building human-centered artificial intelligence. However, there exists no robust method to detect contact between the body and the scene from an image, and there exists no dataset to learn such a detector. We fill this gap with …
