Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Reproducibility Variable Result LLM Response
Research Type Experimental We evaluate our DC4GS on the three standard datasets: Mip-Ne RF 360 [2] (five outdoor and four indoor scenes), and two scenes each from Tanks and Temples [16] and Deep Blending [12], following the 3DGS [14]. Every 8th frame is used for test. Rendering quality is evaluated by PSNR, SSIM [35], and LPIPS [43]. We also report memory requirements for 3DGS parameters and the number of primitives to assess storage efficiency.

Open Datasets Yes We evaluate our DC4GS on the three standard datasets: Mip-Ne RF 360 [2] (five outdoor and four indoor scenes), and two scenes each from Tanks and Temples [16] and Deep Blending [12], following the 3DGS [14].

Dataset Splits Yes Every 8th frame is used for test.
Hardware Specification Yes All the experiments are conducted on a single NVIDIA A6000 GPU with 48GB of memory.
Software Dependencies No Our DC4GS can be integrated seamlessly into the existing 3DGS pipelines. We implemented ours on top of the 3DGS [14], as well as its recent extensions: Pixel-GS [44] and Abs GS [38].
Experiment Setup Yes To ensure a fair comparison with the baselines [14, 38, 44], we adopt their training schedules, loss functions, and all hyperparameters, including the gradient threshold τp and the scale threshold τS. As with the baselines, we halt the densification after 15K iterations. In our implementation, we empirically set the samples of N=5.
