We provide a demo video, named `demo_EcoSplat.mp4', that showcases more abundant visualization results.
The demo consists of two parts: (i) efficiency-controllable NVS results on the RE10K test dataset, and (ii) efficiency-controllable NVS results on the ACID test dataset with cross-dataset generalization.
For both parts, we train each model using the RE10K training dataset. We use 24 input views for inference.
For each video, we first reduce the number of primitives for each method from 100% of the pixel-aligned Gaussians to 5%, and then present the NVS results for all intermediate views between the first and last indices of the input images using only 5% of the primitives.
Note that GGN cannot reduce the number of primitives below 15% due to its architectural limitations for pruning.
The demo video demonstrates that EcoSplat faithfully controls the number of primitives while preserving perceptual quality, whereas the other baselines exhibit a substantial drop in visual quality.
