I have a vector of data, which contains integers in the range -20 20. Bellow is a plot with the values:
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
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
I have been doing some experimentations using wavelets on image data in both Mathematica and Matlab. I have identified some piece of code in Mathematica that seems do basically do what I want which lo
I\'m trying to write a simple self-contained program that does a single level of a discrete wavelet transform on a 1D list, using the CDF 9/7 wavelets, and then reconstructs it. I\'m just using the co
I\'m trying to build a scalogram view for my app to see whether there is relevant information we can retrieve from a wavelet transform as opposed to using a 开发者_如何学Gospectograms to see what can
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
I\'m trying to run an integer-to-integer lifting 5/3 on an image of lena.I\'ve been following the paper \"A low-power Low-memory system for wavelet-based image compression\" by Walker, Nguyen, and Che
