DIAL-GS: Dynamic Instance Aware Reconstruction for Label-free Street Scenes with 4D Gaussian Splatting

Read the original on arXiv Computer Vision →

DIAL-GS introduces a dynamic instance-aware reconstruction technique for label-free street scenes using 4D Gaussian Splatting. It identifies dynamic instances by detecting appearance-position inconsistencies between warped renderings and actual observations, then employs instance-aware 4D Gaussians to create a unified volumetric representation that adapts to dynamics. A reciprocal mechanism further strengthens identity and dynamics, leading to improved reconstruction quality and instance-level editing compared to existing self-supervised baselines.

IGGT4D: Streaming 4D Instance-Grounded Geometry Transformer

Real-world spatial intelligence requires agents to understand scenes from continuous video streams, where objects move, persist, disappear, and reappear over time. While recent spatial foundation models have enabled generalizable feed-forward 3D reconstruction, most streaming methods remain geometry-centric and lack temporally consistent object-level understanding.

WilLaGS: Latent-Conditional 3D Appearance Fields for Robust Gaussian Splatting In-the-Wild

WilLaGS introduces a unified framework that enhances 3D Gaussian Splatting for in-the-wild scenes by learning a continuous global appearance manifold with a β‑VAE and generating dynamic Tri‑Plane features for spatially‑varying local illumination. It also incorporates a self‑supervised perceptual masking mechanism using a Teacher‑Student EMA architecture to suppress transient artifacts and identify inconsistent regions. Experiments on multiple datasets show that WilLaGS achieves state‑of‑the‑art reconstruction quality and novel view synthesis while preserving real‑time rendering efficiency.
