There it is!
I have dropped hints from time to time but never requested this myself. I use this all of the time! I normally call it secret sauce or local contrast in my PlayRaws but it is really CLAHE in action.
In particular, Mr Schatz’s implementation pnmclahe usually gives me what I need, which I compiled for win7. However, it only works for 8-bit or 16-bit ppms or pgms. CLAHE being around for ages has had slightly different implementations in various software but pnmclahe remains my favorite.
Another implementation worth mentioning, besides larger packages like opencv and the like, is @snibgo’s eqlTile.bat.
@David_Tschumperle @Carmelo_DrRaw: please consider adding CLAHE to your respective apps.
