Aug 7, 2021 · The discrete wavelet transform is applied in many areas, such as signal compression, since it is easy to compute. I notice that, However, the continuous wavelet …

Apr 7, 2014 · What is the difference between soft thresholding and hard thresholding. Where we use soft and hard thresholding in image for denoising. I understand that in hard thresholding, …

May 6, 2015 · I'm trying to looking the meaning and functionality about scaling function and wavelet function at wavelet analysis. I have googling already. But I can't find and understand …

Jan 13, 2023 · How can power or energy be computed from Continuous Wavelet Transform? Is it just $\sum |\text {CWT} (x)|^2$, or are there other considerations, particularly if interested in a …

Jul 8, 2024 · I am using the Synchrosqueezing Wavelet Transform and I want to compare it to classical CWT. For this, I use a signal consisting of a chirp. Strangely, in the SST result, it …

Dec 14, 2021 · Wavelet transforms and short-term/short-time Fourier transforms are broad names for classes of transformations that are not totally distinct and may overlap (pun intended). Both …

Jul 17, 2021 · Mathematically, once the mother wavelet is parameterized, change in scale is a uniform shift of the wavelet in log-frequency - hence, peak center frequency is exactly …
