Diffusion models guided by affordances improve 3D hand reconstruction

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method for reconstructing 3D hand poses, particularly in scenarios with significant occlusion. Their approach leverages affordance-guided diffusion models, inspired by human contextual reasoning, to refine hand poses. By conditioning a diffusion model on textual descriptions of hand-object interactions (HOI) inferred from a vision-language model (VLM), the system generates more accurate and functionally coherent poses for occluded regions. Experiments on the HOGraspNet dataset show substantial improvements over existing regression and non-contextual diffusion-based refinement methods. AI

IMPACT This research could lead to more robust 3D hand tracking in applications like robotics and augmented reality, especially in complex, occluded environments.

    Affordance-Guided Diffusion Prior for 3D Hand Reconstruction

    arXiv:2510.00506v2 Announce Type: replace Abstract: How can we reconstruct 3D hand poses when large portions of the hand are heavily occluded by itself or by objects? Humans often resolve such ambiguities by leveraging contextual knowledge -- such as affordances, where an object'…
