Whoever created this page did a nice job. Solid information and well written. jeffo 14:50, 29 Jul 2004 (UTC)
Examples, formulas, and perhaps sample images would be of benefit. The article in its current form seems to appeal mostly to people already familiar with the subject. A good start, though. Rethunk 20:06, 8 Jun 2005 (UTC)
- I wrote this page. Thanks. I put a lot of time and effort into writing a thorough introduction to the subject in [http:// www.ffconsultancy.com/free/thesis.pdf my PhD thesis]. I also contributed significantly to research in this area (see the Hilbert-Hermitian wavelet) and commercialized my work in the form of [http:// www.ffconsultancy.com/products/CWT/ a Mathematica add-on]. If you want to do time-frequency analysis accurately, the maths gets very hard very quickly. So I'm not sure it belongs on Wikipedia. Maybe a cutdown version based on Gabor/Morlet would be ok.

If I am not mistaken, the set in the paragraph named Quadratic forms is always convex as it is always empty. I do not the correct version of this statement, I am guessing that it should read something like If for every the set is convex, then the QTFR is cross-term free.
Yea, I agree, the set is always empty since . I don't know what the correct version is, and I wasn't able to find it in Jon Harrop's thesis, but I think your suggestion of pulling the "for every " out of the set comprehension is the most sensible thing to do. -- Tuckerleavitt (talk) 01:54, 25 September 2017 (UTC)
