We seek clarification of the goals of this new working group effort. It does not seem clear that any specific need for such new work has been identified. The goal of being "competitive" with standards in widespread use seems to be describing a basically undesirable attribute of a standards development activity, which should presumably be to achieve interoperability and to focus industry efforts rather than to compete with other well-developed technologies.

  • Quality and Rate Control of Jpeg Xr
    QUALITY AND RATE CONTROL OF JPEG XR A Thesis by YIDING LIU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Zixiang Xiong Committee Members, Erchin Serpedin Ulisses Braga-Neto Jyh-Charn Steve Liu Head of Department, Miroslav M. Begovic August 2016 Major Subject: Electrical Engineering Copyright 2016 Yiding Liu ABSTRACT Driven by the need for seismic data compression with high dynamic range and 32- bit resolution, we propose two algorithms to efficiently and precisely control the signal- to-noise ratio (SNR) and bit rate in JPEG XR image compression to allow users to compress seismic data with a target SNR or a target bit rate. Based on the quantization properties of JPEG XR and the nature of blank macroblocks, we build a reliable model between the quantization parameter (QP) and SNR. This enables us to estimate the right QP with target quality for the JPEG XR encoder. ii DEDICATION To my father, Dr. Xiaoyang Liu, and my mother, Wei Han. iii ACKNOWLEDGEMENTS I would like to especially thank my committee chair, Dr. Zixiang Xiong, and my committee members, Dr. Erchin Serpedin, Dr. Ulisses Braga-Neto and Dr. Jyh-Charn Steve Liu, for their guidance and support throughout the course of this research. Thanks also go to my friends and colleagues, Bo Wang, Ziwei Xuan and Yan Meng for making my time at Texas A&M University a great experience. Finally, thanks to my father, mother and Nan Jiang for their encouragement, support and love.
