Abstract
Techniques to handle the Spherical Harmonic (SH) coefficients associated with 3DGS towards effective compression are described herein. SH coefficients are used to represent view dependent RGB color values, which takes a significant amount of memory—48 out of 59 parameters per Gaussian. By applying suitable transformation to SH coefficients, the inter-channel redundancies are exploited, thereby effectively reducing the memory requirements by 50%.
