NEC has developed a remote system to provide tour guide and interpretation services to foreign tourists in their native languages. This system was made possible by combining wearable computer and unified communication technology, enabling two-way real-time visual and audio communication even while foreign tourists are on the move. Field tests were performed at "specified ubiquitous districts (tourism-oriented country)" in Kyoto as certified by the Japanese Ministry of Internal Affairs and Communications, in order to evaluate viability from the standpoints of technology and service.

NEC has been providing an enterprise oriented rental service featuring a "Communication Robot, PaPeRo." As a part of this service, we have produced a prototype of a "telecommunication robot (a mobile robot performing telecommunication)" that is capable of communicating with people while being operated from remote locations and we are currently undertaking further research and evaluation. A user remotely controls the robot via a PC by watching the images that the robot captures with its camera eyes. This enables smooth communication between a person remotely operating the PaPeRo and those sitting in front of it. The history of communication tools has been progressed via telephone and videophone. The "telecommunication robotsuggests a new possibility of a communication tool in next generation.

Keeping pace with recent advances in information and communication technologies and device technologies, video and other images have become a more integral part of our lives, while the scope of the application of imaging technologies has continued to broaden. Over its long history, NEC has pioneered development in imaging technologies and contributed to achievements in many fields from broadcasting video to image recognition. Applying these highly sophisticated imaging technologies, NEC is providing solutions that are answering and anticipating customer needs. This special issue will provide a general explanation of NEC's pursuit of imaging and recognition technologies by giving the reader a historical review and an outline of NEC's achievements in the fields of "Imaging capture and transmission technology," and "Imaging analysis and processing technology." With a focus on the three areas of "Image recognition/analysis," "Image accumulation/processing," and "Image distribution," this article will introduce various imaging solutions that incorporate the application of these technologies and create new value for users.

The video monitoring system was initially introduced for collection and recording of the video recorded by surveillance cameras. However, when it is combined with an image analysis technology it is expected to become a tool for improving the efficiency and functionality for the safety and security services. By targeting the implementation of a video monitoring system as an IT safety/security tool, NEC is developing a metadata analysis technology that is capable of the efficient extraction of specific images or information from the large amount of video collected by surveillance cameras according to purpose. This paper overviews the component technologies of the metadata analysis technology, focusing on the characteristics of vehicles and humans, including license plate recognition, super-resolution processing, vehicle features model matching, human face/clothing feature extraction and human feature model matching. It also introduces solutions that are applied to these technologies.

Previously, image analysis software for human behavior was considered to be an optional extra. Recently, however, image analysis software acting as a business supporting tool has been gaining importance, and the scale of video monitoring systems is becoming larger with the spread of monitoring cameras and trends toward networked equipment. We at NEC, as well, aim to realize a video monitoring system for security which supports operators watching video monitors to become aware of abnormal states. In order to realize the system, we are attempting to put analysis technologies for human behavior into practical use. For automatically detecting prohibited activity and dangerous behavior, persons are automatically detected among the images captured by monitoring cameras, and these persons are tracked by the monitoring cameras. The obtained information is analyzed in real time in accordance with the rules preset for monitoring. This paper explains the technical problems related to the analysis of human behavior and our approaches to solving these problems. In addition, we would like to introduce examples of the applications of analysis technologies working in conjunction with associated systems.
