Still image compression analysis

JPEG2000 is the latest ISO/IEC standard for still image coding. Its core part has already been published as an international standard (IS), and work on its subsequent parts is under way. In This work author´s encoder implementation compliant with core part of JPEG2000 will be presented, as well as results of comparison between presented JPEG2000 encoder implementation and two publicly available JPEG and JPEG-LS implementations. Also, main features of JPEG2000 standard in comparison to somewhat older JPEG and JPEG-LS international standards will be briefly described.
