The images historically used for compression research (lena,
barbra, pepper etc...) have outlived their useful life and
its about time they become a part of history only. They are
too small, come from data sources too old and are available
in only 8-bit precision.
These high-resolution high-precision images have been carefully selected to aid
in image compression research and algorithm evaluation.
These are photographic images
chosen to come from a wide variety of sources and each one
picked to stress different aspects of algorithms. Images are
available in 8-bit, 16-bit and 16-bit linear variations, RGB
and gray.

You are encouraged to use these images for image
compression research and algorithm evaluation. Suggestions
for further improvements are
always welcome.

images at same time. You can also checkout results of
various lossless and lossy compression algorithms on these
images.
