J2K DECODER

CODEC OVERVIEW

JPEG2000 is an image compression standard published as ISO/IEC 15444 as well as ITU-T T.800. It was created by the JPEG Group in year 2000 with the intention of superseding the JPEG standard created in 1992. It offers a superior performance at lower bit-rates, has an embedded resolution and quality scalable architecture, provides options for region of interest (ROI) coding, and is flexible code-stream format that offers better error resiliency. Each image component is divided into independent tiles and is compressed separately . JPEG2000 supports both lossy and lossless compression modes. It is intended for applications such as digital cinema, remote sensing, medical imaging, digital still camera, and digital imaging.
