Gabor wavelets are wavelets invented by Dennis Gabor using complex functions constructed to serve as a basis for Fourier transforms in information theory applications. They are very similar to Morlet wavelets. They are also closely related to Gabor filters. The important property of the wavelet is that it … See more The motivation for Gabor wavelets comes from finding some function $${\displaystyle f(x)}$$ which minimizes its standard deviation in the time and frequency domains. More formally, the variance in the position domain is: See more • MATLAB code for 2D Gabor wavelets and Gabor feature extraction See more When processing temporal signals, data from the future cannot be accessed, which leads to problems if attempting to use Gabor functions for processing real-time signals that depend … See more • Gabor transform • Gabor filter • Morlet wavelet See more WebMar 12, 2024 · 4.
