TL;DR - PointSplat, an ECCV 2026 paper from Zhejiang University, ByteDance, and CUHK-Shenzhen, proposes a compact, feed-forward 3D Gaussian Splatting framework for reconstructing humans from sparse multi-view images. It reduces redundant representations by organizing Gaussians around the person rather than independently around each camera view.
- Replaces view-centric prediction, which repeatedly encodes the same subject across views, with a shared human-centric 3D representation.
- Estimates a coarse human proxy and uses ray casting to remove irrelevant or invisible points before Gaussian prediction.
- A Point-Image Transformer fuses multi-view geometry and appearance into Gaussian position, scale, rotation, opacity, and visual attributes.
- Targets compact, generalizable 3D human reconstruction for bandwidth- and compute-sensitive applications such as immersive live streaming.
