Beyond Co-Localization: DeepCoEx Learns Exclusion-Aware Spatial Representations in Mass Spectrometry Imaging via Dual-Contrastive Learning

Abstract Mass spectrometry imaging (MSI) provides spatially resolved molecular profiles, yet the existing computational workflows are heavily biased toward co-localization and remain limited in characterizing exclusion-like spatial relationships, especially when reliable negative...

Cross modal reliable pixel contrastive learning for incomplete modal brain tumor segmentation

<title>Abstract</title> In clinical practice, Magnetic Resonance Imaging (MRI) often lacks specific modalities, inevitably leading to a degradation in predictive performance. Different modes are currently treated as independent and non-interfering during training for modal featur...
