Following the amendments to Japanese industrial standards (JIS) regarding web accessibility in 2010, NEC enhanced the associated in-house tools and developed a new test tool for Web Accessibility-JIS standards. This tool implements features that include "batch processing,""conformance level capability" and "iterative testing." Its function is to support visual checking work and the "tests results output." Additionally, the "large-scale site testing capability" feature has been inherited from a previous tool. A color testing tool has been developed, which has improved the efficiency of the testing by means of its color vision deficiency simulation function, testing using contrast judgment formulae, the presentation of "recommended colors" and a character recognition technology. These tools are currently used as the standard tools for in-house software development. Source

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. Source

Computerization and the consequent diffusion of network services have been increasing the need for biometrics year on year. Face recognition is a technology that imposes a low work load on users because it is based on natural authentication movements, such as viewing a camera. NEC Information and Media Processing Laboratories first joined the Facial Recognition Evaluation Program of the U.S. National Institute of Standards and Technology (NIST) in 2009.Top ranking in recognition accuracy and search speed tests was awarded in the three consecutive years; 2009, 2010 and 2013. This paper describes the NEC face recognition technologies that achieved the top ranking performances, and discusses the results achieved in the NIST evaluation program of 2013. Source

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.

NEC's video identification technology enables instant video content identification by extracting a unique descriptor called a "video signature" from video content. This technology is approved as the MPEG-7 Video Signature Tool; an international standard of interoperable descriptors used for video identification. The video signature is an extremely robust tool for identifying videos with alternations and editing effects. It facilitates search of very short video scenes. It also has a compact design, making ultrafast searches possible via a compact system. In this paper, we propose video identification solutions for the mass media industries. They adopt video signatures as metadata descriptions to enable efficient video registration operations and the visualization of video content relationships. Source
