- hinkley 3y agoHuh. In all of those years when people were talking about wavelets being the ultimate solution to JPG artifacts (on square boundaries) , nobody ever mentioned that they were built on a square wave function. They just talked about being able to move the positions and adjust the diameter arbitrarily. I have to say I'm a little annoyed.
- Jaxan 3y agoFor jpg2000 other wavelets are used not the square ones. Regular jpg is cosines.
