The JPEG 2000 standard, finalized in 2001, defines a new image -coding scheme using compression techniques based on wavelet technology. Its architecture is useful for many diverse applications, including Internet image distribution, security systems, digital photography and medical imaging. A lot of confusion exists as to what JPEG 2000 is and. For example, for an 512 by 512 image, F = max(1, round(512/256)) = 2, so the image should be averaged within a 2 by 2 window and downsampled by a factor of 2 before applying ssim_index.m.
