Quadratic Gaussian Splatting: High Quality Surface Reconstruction with Second-order Geometric Primitives

ICCV 2025poster

We propose Quadratic Gaussian Splatting (QGS), a novel representation that replaces static primitives with deformable quadric surfaces (e.g., ellipse, paraboloids) to capture intricate geometry. Unlike prior works that rely on Euclidean distance for primitive density modeling--a metric misaligned wi…

Tile-wise vs. Image-wise: Random-Tile Loss and Training Paradigm for Gaussian Splatting

ICCV 2025poster

3D Gaussian Splatting (3DGS) has drawn significant attention for its advantages in rendering speed and quality. Most existing methods still rely on the image-wise loss and training paradigm because of its intuitive nature in the Splatting algorithm. However, image-wise loss lacks multi-view constrai…

MetaGPT: Meta Programming for A Multi-Agent Collaborative Framework

ICLR 2024oral

Recently, remarkable progress has been made on automated problem solving through societies of agents based on large language models (LLMs). Previous LLM-based multi-agent systems can already solve simple dialogue tasks. More complex tasks, however, face challenges through logic inconsistencies due t…
