== Overview ==

JPEG 2000 is a wavelet based image encoding standard. See the article "[[JPEG2000 file design for the Helioviewer Project]]" for details pertaining to the specific JPEG 2000 parameters used in Helioviewer, as well as the motivation for choosing those parameters.

*[http://www.jpeg.org/jpeg2000/CDs15444.html Committee drafts of the standards] Very technical, though extremely useful. Official ISO documents cost $$$, these are free though not 100% up to date.
