CompactSplat: Spatially Adaptive Gaussian Distribution for Feedforward Scene Reconstruction

One-line takeaway

SJTU's CompactSplat performs feed-forward sparse-view 3D reconstruction with spatially adaptive Gaussian allocation instead of uniform per-pixel Gaussians, exploiting planar geometric priors to cut redundancy in homogeneous regions and improve structure.

上海交大的 CompactSplat 是前馈式稀疏视角 3D 重建：不再给每个像素平均分配高斯，而是按空间自适应分配，利用平面等几何先验，减少平坦区域的冗余并改善结构建模。
