In this supplementary material for "SCIGS: 3D GAUSSIANS SPLATTING FROM A SNAPSHOT COMPRESSIVE IMAGE", the results of comparative experiments on all the datasets from dynamic scenes and static scenes are shown. The experiment compares our SCIGS against current state-of-the-art SCI decoding methods and state-of-the-art SCI image-based reconstruction method. An additional experiment is conducted to assess the impact of various mask overlapping rates during the SCI image modulated.
