Compressed 3D Gaussian Splatting Model with Residual Rendering

Recently, 3D Gaussian Splatting (3D-GS) techniques have effectively driven the development of novel view synthesis due to the fast rendering speed and high-quality rendering. In this paper, we propose a compressed 3D Gaussian splatting model with residual rendering to enhance rendering quality and reduce storage. In our model, we design a residual rendering strategy to enrich the scene details, which leverages residual Gaussian points to optimize basic Gaussian points and supplement missing information. Additionally, an octree-based geometric compression model is introduced to compress geometric location.
