COMPARISON OF DjVu AND JPEG FOR PHOTOS.
DjVuPhoto, DjVu's wavelet-based image compression technique
is optimal for photos, paintings, and other continuous-tone
images. Here is a head-to-head comparison of DjVuPhoto and
JPEG for photos of various resolutions and qualities.
DjVu can produce files about half the size of JPEG
for the same quality, with the added advantage of
progressive rendering, and low-memory usage. There is also a paper
entitled DjVu: Results and Comparisons
which includes tables of results
comparing the compression ratios of DjVu with other formats for documents
of various types.
