A new paper explores how Convolutional Neural Networks (CNNs) identify blood vessels in medical images, specifically in fluorescence microscopy and retinal fundus photography. Researchers found that pixel intensity is more critical than texture for segmentation, and CNNs can maintain accuracy even when these cues are removed. The study also revealed that CNNs rely on a limited receptive field and struggle to infer complete vessel geometry from shape alone, though global context offers a slight advantage for fundus images.
