The Team of Prof. WAN Shuai from School of Electronics and Information Has Made Further Achievements at the MPEG International Standardization Meeting

2020-05-06 18:44  

In the late April 2020, the 130th meeting of the International Organization for Standardization Moving Picture Experts Group (MPEG, ISO / IEC JTC 1 / SC 29 / WG 11) was held online. The proposal of "Intra occupancy prediction" was officially adopted in the international standard Geometry based Point Cloud Compression (G-PCC), which was jointly completed by Prof. WAN Shuai and her PhD student Zhecheng Wang from School of Electronics and Information, Northwestern Polytechnical University. In addition, their another proposal has been adopted in the standard reference software.

MPEG is an organization established in 1988 by ISO (International Standardization Organization) and IEC (International Electrotechnical Commission), aims to formulate international standards for moving pictures as well as audio signals. It is the main organization for international standardization of multimedia encoding and compression. In 2014, the MPEG 3D graphics coding group began to research and develop tools suitable for advanced immersive applications. In 2017, the call for proposal of point cloud compression was released. The standard of PCC began to be developed in cooperated with many large mobile device manufacturers, well-known international enterprises and universities.

 

Point cloud is a universal format that represents the real 3D world, and can be used in many fields, such as virtual reality, automated driving, immersive video, digital museums, navigation, and geographic information systems. The compression coding of point cloud is one of the important technologies for applying point cloud effectively. The two technical proposals adopted by the standard during this meeting belong to the geometry coding of point cloud, and they have good performance of high compression rate, low computational complexity and low storage consumption.

 

Prof. WAN Shuai and his team have long been invested in standardization, and have maintained long-term cooperation with well-known companies. In 2019, the team contributed 2 technologies in the latest video coding international standard H.266 / VVC (Versatile Video Coding), which is jointly developed by the International Telecommunication Union and the International Organization for Standardization Moving Picture Experts Group (ITU-T SG 16 WP 3 and ISO / IEC JTC 1 / SC 29 / WG 11). The correspondent series of standards has always been the most widely used video coding standard in the world, and is formulated once every 5-10 years.

Prof. WAN Shuai is a member of Multimedia Systems & Applications Technical Committee (MSA-TC) of IEEE Circuits and Systems Society, an Adjunct Professor of RMIT university, Australia, and is currently serving as the the lead TPC co-chair for ICME 2020. She has published the book "New Generation of High-Efficiency Video Coding H.265 / HEVC: Standards, Theories and Implementation". This book has been printed three times and widely praised by readers.

 

Prof. WAN Shuai’s team is affiliated to the Shaanxi Provincial Key Laboratory “Information Acquisition and Processing” and the research group of“Intelligent Optoelectronic Information Detection and Processing”in school of Electronics and Information. The research group has dedicated to research in top international academic filed, including the multimedia communications, intelligent information acquisition and processing. The achievements in the international standards are not only an reward of their long term investment in advanced academic and scientific research, but also a witness of the school's increasing influence in the relevant international standards and related technical fields.
