ArXiv / Project Website / bibtex

FlowIt is a novel transformer-based global matching architecture for optical flow estimation, leveraging a hierarchical transformer design and an Optimal Transport-based flow initialization. FlowIt establish new state-of-the-art results on the Sintel benchmark, as well as zero-shot generalization performance across the Sintel, Spring, and LayeredFlow datasets.

ArXiv / Project Website / Code / bibtex

WarpRF is a training-free framework for quantifying the uncertainty of radiance fields and can be applied to any radiance field implementation. WarpRF excels at both uncertainty quantification and downstream tasks, e.g., active view selection and active mapping, outperforming any existing method tailored to specific frameworks.

This paper addresses the poor geometric accuracy of 3D Gaussian Splatting (GS), which often produces inaccurate depth maps. It proposes a novel training strategy that incorporates depth priors from a stereo network by processing virtual stereo pairs rendered by the 3DGS itself, simultaneously improving the inferred 3D structure and the quality of novel view synthesis.

DepthP+P: Metric Accurate Monocular Depth Estimation using Planar and Parallax

Self-supervised monocular depth estimation methods are typically scale-ambiguous. We show that the planar parallax formulation can resolve this limitation and train a self-supervised monocular depth estimation network producing metric outputs.

In this paper, we assume that there is an underlying process creating observations in a video and propose to factorize it into static and dynamic components. We model the static part based on the scene structure and the ego-motion of the vehicle, and the dynamic part based on the remaining motion of the dynamic objects. By learning separate distributions of changes in foreground and background, we can decompose the scene into static and dynamic parts and separately model the change in each.
