COMPARISONS 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.


SLIDES FROM A TALK COMPARING DjVu TO OTHER FORMATS

These colorful slides from the talk, DjVu Document Browsing with On-Demand loading and rendering of image components, offer graphic comparisons of the flexibility and compression ratios of DjVu and other formats, such as JPEG, JPEG-2000, TIFF/G4, GIF, and PDF, with special attention to the feasibility of these formats for document delivery over the Web. The slides include hyperlinks to real DjVu examples. (Note: this paper is in DjVu. If you do not already have the DjVu Plug-in installed on your system, you will need to download the Plug-in before you can view the slides.)


DjVu COMPRESSION RATIOS COMPARED TO OTHER FORMATS

This paper, DjVu: Results and Comparisons, includes tables of results comparing the compression ratios of DjVu with other formats for documents of various types. (Note: this paper is in DjVu. If you do not already have the DjVu Plug-in installed on your system, you will need to download the Plug-in before you can view it.)
