Foveated Model Observers for Visual Search in 3D Medical Images
TL;DR: A proposed extension of the Channelized Hotelling model (foveated search model) that processes the image with reduced spatial detail away from the point of fixation, explores the image through eye movements, and scrolls across slices can successfully predict the interaction observed in humans and also the types of errors in 3D search.
Proceedings ArticleDOI
Some unlikely properties of the likelihood ratio and its logarithm
TL;DR: Some basic mathematical properties of the likelihood ratio and its logarithm are examined and it is demonstrated that there are strong constraints on the form of the probability density functions for these test statistics.
Journal ArticleDOI

TL;DR: A decision framework based on utility analysis and McNemar’s test provides a decision framework to evaluate predictive models in breast cancer risk estimation, and it is found that SNPs and mammographic features played a significant role in breast Cancer risk estimation.
Journal ArticleDOI
Derivation of a detectability index for correlated responses in multiple-alternative forced-choice experiments.
TL;DR: A rigorous derivation is presented that shows that the modified detectability index, d'r, result generalizes to MAFC tasks in this case.
Book ChapterDOI
Ideal observer model for detection of blood perfusion and flow using ultrasound.
TL;DR: The ideal observer model provides a framework for assessing the performance of Power Doppler ultrasound systems, and may aid in their design.
