Energy Matching: Unifying Flow Matching and Energy-Based Models for Generative Modeling

NeurIPS 2025poster

Current state-of-the-art generative models map noise to data distributions by matching flows or scores. A key limitation of these models is their inability to readily integrate available partial observations and additional priors. In contrast, energy-based models (EBMs) address this by incorporating…

vesselFM: A Foundation Model for Universal 3D Blood Vessel Segmentation

CVPR 2025poster

Segmenting 3D blood vessels is a critical yet challenging task in medical image analysis. This is due to significant imaging modality-specific variations in artifacts, vascular patterns and scales, signal-to-noise ratios, and background tissues. These variations, along with domain gaps arising from…

Physics-Regularized Multi-Modal Image Assimilation for Brain Tumor Localization

NeurIPS 2024poster

Physical models in the form of partial differential equations serve as important priors for many under-constrained problems. One such application is tumor treatment planning, which relies on accurately estimating the spatial distribution of tumor cells within a patient’s anatomy. While medical imagi…
