JPEG2000: Two Compression Options

An image compressed using JPEG2000 but with two different data orderings: "progressive by SNR" and "progressive by resolution." Either of these orders can be produced without expanding and recompressing the data: Once the data are coded, a parsing application can reorder the data by moving coded pieces and altering a small number of header values appearing in the code stream. Final quality can be controlled by a simple truncation of the resulting code stream.

SNR progressive 0.12 bit/pixel	Resolution progressive 0.12 bit/pixel
SNR progressive 0.38 bit/pixel	Resolution progressive 0.38 bit/pixel
SNR progressive 1.25 bit/pixel	Resolution progressive 1.25 bit/pixel
Final image 3.9 bit/pixel
