Abstract

JPEG XT (ISO/IEC 18477), the latest standardization initiative of the JPEG committee defines an image compression standard backwards compatible to the well-known JPEG standard (ISO/IEC 10918-1). JPEG XT extends JPEG by features like coding of images of higher bit-depth, coding of floating point image formats and lossless compression, all of which are backwards compatible to the legacy JPEG standard. In this work, the author presents profiles of JPEG XT that are especially suited for hardware implementations by requiring only integer logic. All functional blocks of a JPEG XT codec are here implemented by integer or fixed point logic. A performance analysis and comparison with other profiles of JPEG XT concludes the work.
