Here is a sonogram of the introduction to “Pictor Alpha” by Curtis Roads.
Now, we make a dictionary of Gabor atoms of various sizes, and decompose this signal into 5000 atoms using MPTK. How can we visualize the output?
One of the easiest ways is by a superposition of the Wigner-Ville distributions of the atoms, scaled by their energy in the decomposition.
This produces the following picture.
The code I used to generate this is here.
Much more can be done to the code by way of software engineering to streamline it; but it is only to serve as a simple example of how to do such visualizations.
Now, time to look at doing the same but in python.
