Retinal vessel segmentation accuracy affected by threshold selection, study finds

By PulseAugur Editorial · [1 sources] ·

A new research paper evaluates the impact of observer choice and threshold selection on retinal vessel segmentation accuracy. The study utilized the CHASE DB1 dataset and analyzed different thresholding policies, including fixed, observer-tuned, and maximin tuning. Results indicated that while maximin tuning altered thresholds in a majority of fits, it offered minimal improvement in worst-observer Dice scores. The paper advocates for explicit reporting of both threshold-selection and evaluation references to ensure clarity in segmentation accuracy assessments. AI

IMPACT This research highlights the importance of standardized evaluation protocols in computer vision, particularly for medical imaging tasks.

    Observer Choice and Threshold Selection in Retinal Vessel Segmentation: A Subject-Separated Evaluation

    arXiv:2609.25597v2 Announce Type: replace Abstract: The annotation used to select a segmentation threshold is part of the evaluation protocol, yet its effect is easily conflated with model quality. We examine this choice for retinal vessel segmentation using all 28 CHASE DB1 imag…
