New OTCHA module improves multi-view medical image classification

Researchers have developed OTCHA, a new module for multi-view medical image classification that uses optimal transport to align latent hub tokens. This method refines patch tokens before fusion, addressing issues with unregistered images and irrelevant background cues that can obscure diagnostic findings. OTCHA incorporates confidence-aware matching and a novel alignment loss to improve robustness across diverse anatomies and view configurations, showing consistent improvements on multiple medical image datasets.
