     [S]                  _       The New Test Images

                                  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.

                                  and algorithm evaluation. Suggestions for further improvements are
                                  always welcome.
