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.
