Wavelet Transform for N dimensions

I came across this amazing response Applying MATLAB\'s idwt2 several times which I executed to understand it myself. However, I am unable to get how to use the same with work with an RGB image. So, I[详细]

EEG Wavelet Analysis

I want to do a time-frequency analysis of an EEG signal. I found the GSL wavelet function for computing wavelet coefficients. How can I extract actual frequency bands (e.g. 8 - 12 Hz) from that coeffi[详细]

Daubechies-4 Transform in MATLAB

I have a 4x4 matrix which I wish to decompose into 4 frequency bands (LL, HL, LH, HH where L=low, H=high) by using a one-level Daubechies-4 wavelet transform. As a result of the transform, each band s[详细]
