Abstract -
It has long been realized that the current JPEG standard does not
provide state-of-the-art performance in its lossless mode.
In view of this, the JPEG committee of the International
Standards Organization (ISO) recently solicited proposals
for a new lossless/nearly lossless still image compression
standard. The proposed standard targets lossless or
near-lossless compression of continuous-tone (2 to 16 bits) still
pictures for medical, satellite and archival images. In
this talk, we shall describe the standardization process
that has now been active for over a year, leading to the
development of a new state-of-the-art standard on lossless
image compression. We shall discuss the main ideas that were
proposed and the major issues that were raised. We will
conclude with the current status of the standard and a
brief description of other work items that the committee
has under consideration.
