It is hard to see a needle in a haystack: Modeling contrast masking effect in a numerical observer
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
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.
Integration of spatio-temporal contrast sensitivity with a multi-slice channelized Hotelling observer
Detection performance of the new observer in digital breast tomosynthesis is measured in a variety of browsing speeds, at two spatial sampling rates, using computer simulations.
