QUBIQ: Uncertainty Quantification for Biomedical Image Segmentation Challenge
CoRR(2024)
摘要
Uncertainty in medical image segmentation tasks, especially inter-rater
variability, arising from differences in interpretations and annotations by
various experts, presents a significant challenge in achieving consistent and
reliable image segmentation. This variability not only reflects the inherent
complexity and subjective nature of medical image interpretation but also
directly impacts the development and evaluation of automated segmentation
algorithms. Accurately modeling and quantifying this variability is essential
for enhancing the robustness and clinical applicability of these algorithms. We
report the set-up and summarize the benchmark results of the Quantification of
Uncertainties in Biomedical Image Quantification Challenge (QUBIQ), which was
organized in conjunction with International Conferences on Medical Image
Computing and Computer-Assisted Intervention (MICCAI) 2020 and 2021. The
challenge focuses on the uncertainty quantification of medical image
segmentation which considers the omnipresence of inter-rater variability in
imaging datasets. The large collection of images with multi-rater annotations
features various modalities such as MRI and CT; various organs such as the
brain, prostate, kidney, and pancreas; and different image dimensions 2D-vs-3D.
A total of 24 teams submitted different solutions to the problem, combining
various baseline models, Bayesian neural networks, and ensemble model
techniques. The obtained results indicate the importance of the ensemble
models, as well as the need for further research to develop efficient 3D
methods for uncertainty quantification methods in 3D segmentation tasks.
