JointDiff: Bridging Continuous and Discrete in Multi-Agent Trajectory Generation

ICLR 2026poster

Generative models often treat continuous data and discrete events as separate processes, creating a gap in modeling complex systems where they interact synchronously. To bridge this gap, we introduce $\textbf{JointDiff}$, a novel diffusion framework designed to unify these two processes by simultane…

Unified Uncertainty-Aware Diffusion for Multi-Agent Trajectory Modeling

CVPR 2025poster

Multi-agent trajectory modeling has primarily focused on forecasting future states, often overlooking broader tasks like trajectory completion, which are crucial for real-world applications such as correcting tracking data. Existing methods also generally predict agents' states without offering any…

Uncertainty-Aware Camera Pose Estimation From Points and Lines

CVPR 2021poster

Perspective-n-Point-and-Line (PnPL) algorithms aim at fast, accurate, and robust camera localization with respect to a 3D model from 2D-3D feature correspondences, being a major part of modern robotic and AR/VR systems. Current point-based pose estimation methods use only 2D feature detection uncert…

Discriminative Learning of Deep Convolutional Feature Point Descriptors

ICCV 2015poster

Deep learning has revolutionalized image-level tasks such as classification, but patch-level tasks, such as correspondence, still rely on hand-crafted features, e.g. SIFT. In this paper we use Convolutional Neural Networks (CNNs) to learn discriminant patch representations and in particular train a…
