Title: The Future Of Similarity Search On High Dimensional Multimedia Data

In this talk, Dr. Liu will briefly introduce the related research topics that are currently conducted at the Central Research Laboratories of NEC Corporation, such as big data processing. He will then focus on the introduction to a commercial level demo system for surveillance video search, named Wally, which will be exhibited at the ACM Multimedia 2014. Wally is a scalable distributed automated video surveillance system with rich search functionalities, and integrated with image processing products developed by NEC, such as NeoFace(R), FieldAnalyst, and StreamPro. Here, NeoFace(R) is one of the best face recognition technologies in the world, having highest recognition accuracy.

Subsequently, Dr. Liu will briefly introduce small pieces of the past work during his Ph.D. study on similarity search, such as k-Nearest Neighbors Search (kNN), Range Search, Reverse k-Nearest Neighbors Search (RkNN), Reverse Furthest Neighbors Search (RFN), etc. Meanwhile, he will report their current progress on indexing techniques for similarity search on high dimensional multimedia data. Finally, he will pick up some challenging issues and share some initial motivations that make us should consider integrating indexing techniques with non-volatile memory (NVM) devices. Such an integration would be helpful to enhance the performance of similarity search on high dimensional multimedia data in the near future.
