Experimental Setup
nStep 1: verified that GIF/JPEG images are predominant causes of WWW bandwidth (GIF: 50%, JPEG 32%)
nStep 2: collect set of “typical” images using Gozilla, resulting in a collection of 1500 images
nStep 3: ensure that images are representative of image
size distributions found on WWW
–led to
additional download of 2000 (smaller) images
nStep 4: select image processing software
(ImageMagick)
–many
operations
–available
in source code
–popular and
well documented
