讲座内容简介：

在过去的几年里， 基于哈希码的最近邻搜索因为其高效的性能获得了学术界的广泛关注，其核心算法已经在很多场景中进行了应用。在这个讲座中，我将用两个自己参加的实例来讲述如何在不同应用背景的情况下使用哈希码，来进行内容识别。第一个实例是展示在工业界如何通过识别语音哈希码来同步不同的媒体设备，比如同步电视和移动终端设备；另外一个实例展示了我们如何从理论的角度来改进著名的ITQ方法，并且证明整个算法的普适性和收敛性。通过讲座，希望大家能够对工业界做研究和学术界做研究的不同有一定认识。

Hashing for Content Identification: from Synchronization to Retrieval

Date of event：2016-9-13

Title of Lecture： Hashing for Content Identification: from Synchronization to Retrieval

Lecturer：Prof. Jungong Han

Venue: 522 room of School of Computer Science, Wenjin Building

Hosted by: School of Computer Science

About the Lecture：

In the past few years, nearest neighbor search methods based on hashing have gained considerable attention for effective and efficient large-scale similarity search, facilitating a variety of applications. In this talk, we will elaborate two recent works, which are audio hashing for multi-screen synchronization and robust iterative quantization for image search. The former extracts hash code from the audio signal and exploits it as a signature for content identification while the latter generalizes a widely-used ITQ algorithm by extending it from L_2 norm to L_pq norm. The intention is to showcase the difference of carrying out research activities in industry and academia.

Profile of the Lecturer：

Jungong Han is currently a Senior Lecturer with the Department of Computer Science and Digital Technologies at Northumbria University, Newcastle, UK. He received his Ph.D. degree in Telecommunication and Information System from Xidian University, China, in 2004. During his Ph.D study, he spent one year at Internet Media group of Microsoft Research Asia, China. Previously, he was a Senior Scientist (2012-2015) with Civolution Technology (a combining synergy of Philips Content Identification and Thomson STS), a Research Staff (2010-2012) with the Centre for Mathematics and Computer Science (CWI), and a Senior Researcher (2005-2010) with the Technical University of Eindhoven (TU/e) in Netherlands.

Dr. Han’s research interests include Computer Vision, Multimedia Content Identification, Multi-Sensor Data Fusion and Multimedia Security. He has written and co-authored over 90 papers including 3 invited papers in these areas. His first-author paper published in 2013 has to date been cited for more than 450 times, which is recognized as one of the pioneering works in the field of depth based computer vision. Apart from publishing scientific articles, Dr. Han also dedicates to transferring the academic achievements to the commercial products. During his employment with TU/e, his software (C implementation of the proposed algorithm) has been commercialized and utilized by a start-up company. During the period of working in Civolution, his Audio Fingerprinting algorithm was implemented in SyncNow product, which won several industrial awards.

He is an Associate Editor of Elsevier Neurocomputing and an Editorial Board Member of Springer Multimedia Tools and Applications. He served as TPC member, Session Chair, and the reviewer for various conferences and journals. He has been (lead) Guest Editor for five international journals, such as IEEE-T-SMCB, IEEE-T-NNLS, Pattern recognition letters and Neurocomputing. Since 2009, he is a voting member of IEEE Multimedia Communications Technical Committee (MMTC). Since 2012, he has been a member of IEEE Industry DSP Technology Standing Committee. Dr. Han was the recipient of the UK Royal Society Newton Mobile Award in 2016.
