Deletion of Hermitian hat wavelet

Comment: Fails . Coverage of this subject in published reliable sources seems limited to: https://spie.org/Publications/Proceedings/Paper/10.1117/12.271774?SSO=1 this conference proceedings and https://www.spiedigitallibrary.org/conference-proceedings-of-spie/3078/0000/Wavelet-detection-of-singularities-in-the-presence-of-fractal-noise/10.1117/12.271770.short this conference proceedings, both involving the {{tq|Szu in 1997}} mentioned in this article. Besides this supposed PhD thesis, this hasn't received attention anywhere else. Besides the now-deleted Hilbert-Hermitian wavelet, the article Morlet wavelet is also based on the same PhD thesis (as {{diff2|121349385|mentioned here

Comment: It doesn't qualify as  if it has been published in a PhD thesis, those are generally reliable sources. The problem is lack of notability. Given the lack of interest in the article, the completely absence of sources (including the PhD thesis it supposedly comes from), and the fact that the sister article was also deleted for lack of notability, I assume it's also not notable

Comment: I'm not finding substantial discussion in reliable, secondary sources that are independent of the originator. This seems to fall into that all-but-|OR region: it was technically published somewhere else first, but the same people who wrote that wrote this, and nobody else has paid real attention to it
