Applications


E-commerce acceleration Batch Digimarc watermarking Document archiving ISP bandwidth saving Disk storage space reduction Uploaded image resize and optimize
Features:


Command driven, so can be easily called from other programs or scripting languages Uses MagiCompress technology to optimize all the images on a disk or directory with a simple command. Digimarc invisible watermarking Visible watermarking Up to 2x more compression than a standard JPEG Speed up web pages and save disk space Save $100,000s in bandwidth charges and storage costs Reduce server load Makes 100% compatible JPEGs Resize images GIF, PNG, TIF read and write Automatically create thumbnails and HTML index files Unix versions available
Resizing, Thumbnailing and Indexing


JPEG Disk Optimizer supports resizing and the ability to
generate thumbnails and an HTML index file automatically (Windows only).

The following table was automatically generated from 8 larger images.




The command used was:
jdo -sv -q 95 -m 40 -rw 100 -rb -t 4 *.jpg

Remove spots, dead pixels and noise


JPEG Disk Optimizer version 2.6 adds powerful image
enhancement facilities. The -c switch allows you to remove spots (or
dead pixels) and gaussian noise from the image. This can significantly
improve the appearance of the image as well as make the image smaller:



Image enhanced and
optimized with jdo.
9,705 bytes
Standard JPEG
23,844 bytes
Original Image
61,205 bytes

The command used was:
jdo -q 90 -m 30 -cn 30 diver.jpg

Digimarc Watermarks (Windows)


JPEG Disk Optimizer includes the ability to add Digimarc invisible digital watermarks.

At their most basic level, watermarked images are
"marked" as uniquely yours. They communicate that the image is
copyrighted. Watermarked images also increase e-commerce and online
marketing opportunities because their special embedded code actually
allows them to do things. Digimarc images can:


  • Help you find your images, wherever they go: Digimarc
    watermarked images become "homing beacons" on the World Wide Web. By
    using MarcSpider, you can track where and when your images have been
    moved or copied on the publicly indexible Web.
  • Take you places: More than just a hyperlink, Digimarc
    watermarked can take viewers to a web site, a licensing database, an
    image archive, an internal asset management system, and much more.
  • Announce your copyright: as previously described and reduce potential misuses of your images.

Anyone who licenses or publishes images, or uses them in
marketing campaigns can benefit from Digimarc watermarking. A national
museum currently uses them to communicate ownership of its often-copied
artwork. A record company tracks the use of its musicians' photographs
throughout the Internet. A major stock photo agency embeds watermarks
that link to their company name and contact information into all their
digital photos. Digimarc watermarked images serve as "mini ads" for
their company.

How noise reduction improves Digimarc Watermarking

Digimarc invisible watermarks are not in
fact fully invisible but add what looks like noise to the image. The
greater the intensity and durability of the watermark the more visible
the noise will look.

xat.com's noise reduction technology can
help you minimise the appearance of the watermark and also increase the
intensity of watermark you use.

The images below show enlarged areas of the same image with different settings.

You can see that image D is considerably
more noisy as it contains noise from the original image added to the
watermarking signal.
Image C and D contain the same intensity of watermark so
image C has would allow for increased watermarking intensity to give
your image greater protection.
As a bonus image C will be easier to compress than image D and will have a smaller file size.



A. Original image
B. Noise reduced
C. Noise reduced and watermarked
D. Watermarked

To download the new free Digimarc ImageBridge™ reader for
Windows that will detect and flag watemarked images in your browser click here.

Example usage:


jdo -q 50 -d -s D:\*.jpg

Compress all JPEGs on drive D: with quality level 50. Write a summary of space saved at the end.

Visible Watermarks and text annotation (Windows)


JPEG Disk Optimizer 3.10 and above includes the ability to place another picture on the images and to add text to the image e.g:



In the above image, an xat.com logo has been placed over
most of the image as a very transparent watermark and the file name has
been added to the top right hand corner. Note that in this case an alpha
channel is used to make parts of the logo fully transparent.

The command used was:

jdo -q 95 -m 20 -vf xat.tif -vl bl -vm 0 4 -vo 15 -tt +f.jpg -tc#000080 -tf times 30 -tl tr -tm 8 2 flags.jpg
