Wikipedia:Articles for deletion/Hermitian hat wavelet
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
