Hush: Holistic Panoramic 3D Scene Understanding Using Spherical Harmonics
SOCIAL MEDIA DESCRIPTION TAG TAG
🌟 Key insight: SH basis functions seem geometrically aligned with the signals ( e.g., depth/normal) on the unit sphere! Our approach focuses on a unified framework adaptable to various 3D scene understanding tasks via SH bases. Experiments demonstrate that HUSH achieves state-of-the-art performance on depth estimation benchmarks, highlighting the robustness and scalability of using SH in panoramic 3D scene understanding.
