Abstract:

Mr. Nishimura 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 has been 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. Meanwhile, he will report their current progress on indexing techniques for similarity search on high dimensional multimedia data.

Subsequently, Mr. Nishimura will briefly introduce small pieces of the past work on multi-dimensional index for location based services, named MD-HBase, which has been presented at the MDM 2011. MD-HBase is designed to achieve both scalability and efficiency for querying location data. Meanwhile, he will report their current progress on the extension of MD-HBase. Finally, he will pick up some challenging issues and share some initial motivations that make us should consider integrating both low and high dimensional indexes. Such an integration would be helpful to enhance the functionalities on multimedia information retrieval in the near future.
