## Abstract

<div style="text-align: justify">
The ability of an observer to perform a specific task on images, produced by a given medical imaging systems, defines an objective measure of image quality.

If the observer is “numerical”, can deep learning methods “do the job”? What we found in the literature? Some papers rise this issue and propose to approximate the Ideal Observer for performing tasks detection and localization.
