• Abstract: Recent generative models can synthesize high-quality images but often fail to generate humans interacting with objects using their hands. This arises mostly from the model's misunderstanding of such interactions, and the hardships of synthesizing intricate regions of the body. In this paper, we propose GraspDiffusion, a novel generative method that creates realistic scenes of human-object interaction. Given a 3D object mesh, GraspDiffusion first constructs life-like whole-body poses with control over the object's location relative to the human body. This is achieved by separately leveraging the generative priors for 3D body and hand poses, optimizing them into a joint grasping pose. The resulting pose guides the image synthesis to correctly reflect the intended interaction, allowing the creation of realistic and diverse human-object interaction scenes. We demonstrate that GraspDiffusion can successfully tackle the relatively uninvestigated problem of generating full-bodied human-object interactions while outperforming previous methods.

  G-HOP is a denoising diffusion based generative prior for hand-object interactions. We represent the human hand via a skeletal distance field to obtain a representation aligned with the signed distance field for the object. We show that this hand-object prior can then serve as generic guidance to facilitate other tasks like reconstruction from interaction clip and human grasp synthesis.

  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.

  Given an RGB image of an object, we aim to hallucinate plausible images of a human hand interacting with it. We propose a two-step generative approach: a LayoutNet that samples an articulation-agnostic hand-object-interaction layout, and a ContentNet that synthesizes images of a hand grasping the object.

  We present the first framework to synthesize the full-body motion of virtual human characters with 3D objects placed within their reach. Our system takes as input textual instructions specifying the objects and the associated intentions of the virtual characters. We show that our synthesized full-body motions appear more realistic to the participants in more than 80% of scenarios.

Our generative model is able to synthesize high-quality human grasps, given only on a 3D object point cloud.
