HOIDiffusion: Generating Realistic 3D Hand-Object Interaction Data
This addresses a data bottleneck for researchers and developers in robotics and computer vision, though it is incremental as it builds on existing diffusion models.
The paper tackles the scarcity of 3D hand-object interaction data by proposing HOIDiffusion, a conditional diffusion model that generates realistic and diverse data using geometric structure and text inputs, and demonstrates its effectiveness by improving 6D object pose estimation systems.
3D hand-object interaction data is scarce due to the hardware constraints in scaling up the data collection process. In this paper, we propose HOIDiffusion for generating realistic and diverse 3D hand-object interaction data. Our model is a conditional diffusion model that takes both the 3D hand-object geometric structure and text description as inputs for image synthesis. This offers a more controllable and realistic synthesis as we can specify the structure and style inputs in a disentangled manner. HOIDiffusion is trained by leveraging a diffusion model pre-trained on large-scale natural images and a few 3D human demonstrations. Beyond controllable image synthesis, we adopt the generated 3D data for learning 6D object pose estimation and show its effectiveness in improving perception systems.
