Claims

C1strongest claim

Under extreme view sparsity (one 2D atlas comprising 4 input views), DSGS achieves a +5.79 dB BD-PSNR and +0.054 BD-SSIM gain over the DSDE anchor while reducing maximum inter-view Delta IV-PSNR from 17.2 dB to 6.4 dB.

C2weakest assumption

Lossy compression in the transmitted bitstream functions as an implicit low-pass filter that stabilizes feed-forward splat prediction without introducing artifacts that degrade the final rendered views.

C3one line summary

DSGS performs feed-forward 3D Gaussian Splatting on the decoder from one compressed 2D atlas of four views, yielding +5.79 dB BD-PSNR and lower inter-view variance than decoder-side depth estimation.
