Summary

3D Gaussian Splatting (3DGS) is an emerging 3D scene representation in which a scene is modeled as a collection of anisotropic Gaussian primitives characterized by attributes such as position, scale, orientation, opacity, and appearance. Due to its high rendering quality and real-time performance, 3DGS has recently attracted significant interest for immersive media applications.

The Region Adaptive Hierarchical Transform (RAHT) is a hierarchical attribute transform widely used in point cloud compression standards to compact signal energy prior to entropy coding. However, RAHT was originally designed for voxelized point clouds and does not fully exploit the rich structure and correlations present in Gaussian splat representations. This internship aims to investigate novel attribute transform techniques that exploit correlations between these attributes and neighboring Gaussians. The work will explore a range of approaches, including analytical, graph-based, predictive, and potentially learning-based transforms, adapted to the characteristics of Gaussian splat representations. The objective is to achieve improved energy compaction and compression efficiency compared to RAHT while maintaining practical encoding and decoding complexity.

You will be working in the 3D Native Codec team, in the New Media Codecs Group of the Video Lab.
