• Abstract summary: Human-object interactions (HOIs) are crucial for human-centric scene understanding applications such as human-centric visual generation, AR/VR, and robotics. In this paper, we address this challenge in HOI animation from a compositional perspective. We adopt neural human-object deformation to model and render HOI dynamics based on implicit neural representations.

• Abstract: Human-object interactions (HOIs) are crucial for human-centric scene understanding applications such as human-centric visual generation, AR/VR, and robotics. Since existing methods mainly explore capturing HOIs, rendering HOI remains less investigated. In this paper, we address this challenge in HOI animation from a compositional perspective, i.e., animating novel HOIs including novel interaction, novel human and/or novel object driven by a novel pose sequence. Specifically, we adopt neural human-object deformation to model and render HOI dynamics based on implicit neural representations. To enable the interaction pose transferring among different persons and objects, we then devise a new compositional conditional neural radiance field (or CC-NeRF), which decomposes the interdependence between human and object using latent codes to enable compositionally animation control of novel HOIs. Experiments show that the proposed method can generalize well to various novel HOI animation settings. Our project page is https://zhihou7.github.io/CHONA/

  AvatarGO is a novel framework designed to generate realistic 4D HOI scenes from textual inputs. Our framework not only generates coherent compositional motions, but also exhibits greater robustness in handling issues. As the first attempt to synthesize 4D avatars with object interactions, we hope AvatarGO could open new doors for human-centric 4D content creation.

  We propose PixelHuman, a novel rendering model that generates animatable human scenes from a few images of a person. Our method differs from existing methods in that it can generalize to any input image for animatable human synthesis. Our experiments show that our method achieves state-of-the-art performance in multiview and novel pose synthesis from few-shot images.

  We present a new approach for synthesizing novel views of people in new poses. Our synthesis makes use of diffuse Gaussian primitives that represent the underlying skeletal structure of a human. Rendering these primitives gives results in a high-dimensional latent image, which is then transformed into an RGB image by a decoder network.
