UnfoldCRF: Structured Mask Refinement with Image-Conditioned Latent Regions

UnfoldCRF treats refinement as inference in a conditional random field over pixel labels and latent region variables, and zeroing individual messages shows where the corrections come from: the pairwise messages mostly fix boundaries, the region messages mostly fix non-boundary errors.

MVRNet: A Multi-View Refinement Network for Accurate Recognition of Challenging Intracranial Aneurysms in Enhanced 3D CTA Images

The Multi-View Refinement Network is presented, a framework that delivers clinically meaningful performance gains on the most challenging intracranial aneurysm cases and proposes a feature enhancement technique to obtain boundary-clear CTA, an informative supplement to the bone-free CTA, to further reduce the impact of...

Fused Bayesian Flow Networks for Dual-Target Molecular Design

FusedBFN formulates dual-target generation as distribution fusion in a unified continuous parameter space and employs a product-of-experts formulation to incorporate dual-target information throughout the generative process to address the scarcity of dual-target structural data.
