WebThe Gabor filter feature extraction process starts with the application of a two-dimensional Gabor filter which is applied to each image individually. The process is guided by Gabor's uncertainty principle, which states that the product of frequency resolutions and time must be greater than a constant.

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 … Web6.2 The Gabor Uncertainty Principle Gabor proved his uncertainty principle by applying to arbitrary signals the same mathematical apparatus as used in the Heisenberg-Weyl derivation of the uncertainty principle in quantum mechanics. We give our own version of this proof in the chapter appendix (Sec. 6.12.1, p. 144); here our intent is to WebApr 21, 2024 · Abstract Time-frequency analysis is ubiquitous in many fields of science. Due to the Heisenberg-Gabor uncertainty principle, a single measurement cannot estimate precisely the localization of a finite signal in both time and frequency. phillip kepler
