AI medical image segmentation models suffer from "extent leakage" from labels

A new research paper explores "extent leakage" in vision-language models used for medical image segmentation. The study found that these models often rely heavily on information directly copied from the segmentation masks used to generate captions, rather than deriving insights solely from the image and text. This leakage, particularly concerning the size and location of lesions, significantly impacts the models' ability to segment accurately when trained on such data. The researchers propose a new evaluation protocol to differentiate between information learned from the image and information copied from labels. AI
