On anthropomorphic decision making in a model observer
Ali R. N. Avanaki, Kathryn S. Espig, Tom R. L. Kimpe +1
By analyzing human readers' performance in detecting small round lesions in simulated digital breast tomosynthesis background in a location known exactly scenario, we have develope…
It is hard to see a needle in a haystack: Modeling contrast masking effect in a numerical observer
Ali R. N. Avanaki, Kathryn S. Espig, Albert Xthona +3
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 h…
Development and evaluation of a 3D model observer with nonlinear spatiotemporal contrast sensitivity
Ali R. N. Avanaki, Kathryn S. Espig, Andrew D. A. Maidment +3
We investigate improvements to our 3D model observer with the goal of better matching human observer performance as a function of viewing distance, effective contrast, maximum lumi…
Integration of spatio-temporal contrast sensitivity with a multi-slice channelized Hotelling observer
Ali N. Avanaki, Kathryn S. Espig, Cedric Marchessoux +4
Barten's model of spatio-temporal contrast sensitivity function of human visual system is embedded in a multi-slice channelized Hotelling observer. This is done by 3D filtering of…
