jpeg2000 is already implemented in imwrite.
If you are asking about implementing your own algorithm (dct, etc.) then "anyone has any idea" is much too vague for us to answer. Have you looked at the standard that tells you exactly what needs to be done?

so, I'm using the Gonzalez implementation that uses the 9/7 filter, and I want to change the code to test lossless jpeg2000.
