EntropyGS: An Efficient Entropy Coding on 3D Gaussian Splatting
Contributions:
-
A factorized design is proposed to entropy encode 3DGS based on a correlation analysis of Gaussian attributes, indicating a weak correlation, particularly between spherical harmonic AC components.
-
A parameterized design is further proposed using common distributions to govern Gaussian attributes, including rotation, scaling, opacity, and spherical harmonic AC.
-
An adaptive quantization finally completes the design of the entropy encoder, EntropyGS, for pre-generated 3DGS models with competitive rate-distortion performance.
