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 the meaning. …

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 can be …

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, the coefficients below

I'm trying to directly visualize the relation between discrete wavelet transform (DWT) detail coefficients and the original signal/its reconstruction. The goal is to show their relation in an intui...

Sep 7, 2024 · I have read that the Wavelet Transform can be used to create spectogram, the different result is, the resolution between frequency and time is not linear. In another word, lower frequency …

Jan 3, 2019 · How wavelet transform is different from STFT. I'm not able to understand what is resolution in frequency domain means?
