Hash Grid Feature Pruning for Gaussian Splatting

This paper addresses the inefficiency of hash grids in Gaussian splatting due to sparse regions. By pruning invalid features, it reduces storage and transmission overhead, leading to improved rate-distortion performance. The 8% bitrate reduction compared to the baseline is a significant improvement.
