On anthropomorphic decision making in a model observer

no code implementations30 Jun 2015 Ali R. N. Avanaki, Kathryn S. Espig, Tom R. L. Kimpe, Andrew D. A. Maidment

By analyzing human readers' performance in detecting small round lesions in simulated digital breast tomosynthesis background in a location known exactly scenario, we have developed a model observer that is a better predictor of human performance with different levels of background complexity (i. e., anatomical and quantum noise).

Aging display's effect on interpretation of digital pathology slides

no code implementations30 Jun 2015 Ali R. N. Avanaki, Kathryn S. Espig, Sameer Sawhney, Liron Pantanowitz, Anil V. Parwani, Albert Xthona, Tom R. L. Kimpe

The effect of display aging using these display models and images is further analyzed through a human reader study designed to quantify the effects from a clinical perspective.

It is hard to see a needle in a haystack: Modeling contrast masking effect in a numerical observer

no code implementations5 Aug 2014 Ali R. N. Avanaki, Kathryn S. Espig, Albert Xthona, Tom R. L. Kimpe, Predrag R. Bakic, Andrew D. A. Maidment

Within the framework of a virtual clinical trial for breast imaging, we aim to develop numerical observers that follow the same detection performance trends as those of a typical human observer.

Development and evaluation of a 3D model observer with nonlinear spatiotemporal contrast sensitivity

no code implementations24 Mar 2014 Ali R. N. Avanaki, Kathryn S. Espig, Andrew D. A. Maidment, Cedric Marchessoux, Predrag R. Bakic, Tom R. L. Kimpe

The probability p is considered to be equal to the perceived amplitude of the frequency component and thus can be used by a traditional model observer (e. g., LG-msCHO) in the space-time domain.
