ATSplat: Compact Feed-forward 3D Gaussian Splatting with Adaptive Token Expansion
Cho In, Jeonghwan Cho, Mijin Yoo, Gim Hee Lee, Seon Joo Kim
3D Gaussian Splatting (3DGS) achieves high-quality novel-view synthesis by optimizing freely placed primitives in 3D and adaptively densifying them in under-reconstructed regions. However, this scene-adaptive capacity allocation is largely lost in existing feed-forward 3DGS metho…
