The AV-team consisting of Ahmed Tawfik Aboukhadra, Marcel Rogge, Nadia Robertini, Ahmed Elhayek, Abdalla Arafa, Jameel Malik, and Didier Stricker, has been awarded 1st place in the 9th “Observing and Understanding Hands” (ARCTIC) Workshop Challenge, held in conjunction with ICCV 2025. The team presented their winning solution during the workshop program on the 20th October 2025, showcasing their innovative approach to bimanual hand–object reconstruction.

Their method, “GHOST: Gaussian Hand–Object Surface Reconstruction with Geometric Priors,” introduces a highly efficient framework that reconstructs animatable hand avatars and category-agnostic objects from monocular RGB videos. The approach enables realistic hand–object interactions and significantly outperforms previous state-of-the-art methods both qualitatively and quantitatively, while achieving a 13x speed-up over existing techniques.

This achievement marks an important step forward in human motion understanding, opening promising avenues for applications in Virtual Reality (VR) and Augmented Reality (AR).
