Abstract
JPEG XR, a new international standard for image coding, was approved as ITU-T Recommendation T.832 in March 2009, and as ISO/IEC international standard 29199-2 in July 2009. JPEG XR was designed based on Microsoft coding technology known as HD Photo. Since JPEG XR is an emerging new specification, exploration of advanced encoding techniques for JPEG XR is an important area of study. In order to advance understanding of JPEG XR and its capabilities, the development of enhanced encoding techniques for optimization of encoded JPEG XR perceptual image quality is particularly valuable. This paper presents techniques and results focusing on exploring the capabilities of the spatially adaptive quantization syntax of the emerging JPEG XR standard.
