Evidential Uncertainty-Guided Interactive Segmentation of Ultrasound Images

An end-to-end interactive medical-image segmentation paradigm that uses evidential deep learning (Dempster-Shafer theory and Subjective Logic) to estimate pixel-wise predictive uncertainty, then automatically directs interaction prompts to the highest-uncertainty regions to reduce the number of prompts and iterations a user must supply. A trainable calibration mechanism refines the certain/uncertain boundary to make the uncertainty estimates more trustworthy, yielding efficient, specialized segmentation of noisy ultrasound images.
