The UW Image Coder
by
Dane Barney
JPEG2000, the successor to JPEG, is immerging as an
attractive candidate for the future image compression standard.
However, while it offers superior results over most other image
compression techniques, it comes with a long list of fine-tuning
parameters and a highly complex algorithm. We have developed an image
coder that can compete with the performance of JPEG2000 while offering
a much simpler design. The UW Image Coder combines a wavelet
transform, bit-plane ordering, and arithmetic coding to achieve lossy
compression of grayscale images that can match, and occasionally
outperform, JPEG2000.
