The primary difference is that the JPEG 2000 picture transform uses wavelet filters rather than the more common DCT (discrete cosine transform). JPEG 2000 is a good deal more complex than the original JPEG standard, but is also much more capable of rendering superior pictures. The most important development is that the source images can exceed 8-bits resolution—a prerequisite for high-quality imaging. More information ...
