Web2 days ago · For a study, researchers manipulated exogenous temporal attention and the uncertainty of stimulus timing separately and assessed visual performance at attended and unattended moments with different levels of temporal uncertainty. Two Gabor patches were presented consecutively with a variable stimulus onset time during each trial. Webtheory. Gabor s work was largely inspired by Heisenberg s de-velopments in quantum theory, most notably his uncertainty theo-rem of quantum mechanics. Gabor s results look simultaneously at the frequency and spatial domain of a signal, making it ideal for the measure of the modulation transfer function and point-spread function of an imaging ...
WebI think Gabor's uncertainty applies strictly to the unaliased signal we can measure. Then, as you say, another problem is that we have to take time chunks to measure frequency …
