Can we ditch the ASCII art and get a proper graphic? It took me half a minute to figure out that it was a representation of a graph on a cartesian coordinate system. - 19:58, 23 May 2005 (UTC)

## Merger

Seems logical since Haar-like features doesnt seem notable on its own and content could easily be merged here. Hadrianheugh (talk) 04:54, 21 November 2007 (UTC)

Please allow the editors of this strange article to expand it first and make it comprehensible. Every month 20 or so papers are published in scientific or semi-scientific journals that apply wavelets or wavelet-like ideas to some area in engineering, esp. image and speech recognition. Most of those ideas or modifications of standard algorithms are not notable enough for inclusion, except they could get get a strong and long-living support/care from several editors.--LutzL (talk) 09:15, 21 November 2007 (UTC)
I left this message in talk:Haar-like features 62.93.183.215

”Hi. Just came up to read about the subject (I study bioinformatics) and found the article fine (needs some improvement though). As the previous commenter I don't see it appropiate to merge it with Haar-wavelet. Many people, like me, needs more information about the topic and is able to understand this subject, but does not have any idea about what a wavelet is. Keep it simple please.″

I do not think Haar-like features should redirect here, as they are completely different topics. And since Haar-like features are one of the more common (and successful) approaches to machine vision, I would consider that notable. On the other hand, I do think Haar transform should point here.

I agree with Maghnus, we should merge Haar transform into this article.

I also think Haar transform should be merged here. Thenub314 (talk) 06:46, 16 December 2008 (UTC)

Is it really a complete system? What about $t \mapsto 1$ and $t\mapsto\psi_{0,0}(t)$? —Preceding unsigned comment added by 193.40.36.163 (talk) 08:30, 9 November 2010 (UTC)
