    “The visibility of a target object may be affected by the specific properties of the background scene at and near the target's location and by how uncertain the observer is from one occasion to the next about the values of the background and target properties,” according to a study from Stephen Sebastian, PhD, and fellow researchers at the University of Texas. Visual detection thresholds increase approximately linearly along all three dimensions, and detection accuracy is unaffected by background bin and target amplitude uncertainty, according to research published in the Proceedings of...
