Hitachi Leverages AI for Image-Analysis
March 27, 2017
Hitachi has developed a detection and tracking technology using artificial intelligence (AI) which can distinguish an individual in real-time using features from over 100 categories of external characteristics such as sex, color of clothing or carried items, and immediately detect and track the person sought after individual. Using this technology, it will be possible to detect a suspicious individual or a lost child using information from eye-witness accounts to detect a person fitting that description from public security cameras set up in large facilities or city areas. Further, by analyzing the entire image of the person detected, it will be possible to follow the person from camera images where only the rear-view is captured and the face cannot be seen, or the person is captured from a distance. Hitachi will apply this technology to wide-area security and surveillance systems(1) such as those in public areas, contribute to public safety and security.
To ensure safety, measures such as
surveillance using security cameras and
patrol by security staff are being
implemented in public areas such as city
areas and large facilities such as airports
and stations. In order to prevent
emergencies, however, it is necessary to be
able to immediately close-in on images of a
suspicious person or a lost child based on
eye-witness accounts from persons on the
scene, and locate in real-time the
whereabouts of the person sought after from
the wide-area surveillance camera network.
As it is difficult to screen all of the
images with a limited number of staff,
technology to detect and track people has
been developed using facial images procured
at some entry point or features such as
color of clothing, however it was difficult
to detect and track a person if there was
limited eye-witness account, other people
wearing similar color clothing, or if the
surveillance camera was unable to capture a
clear facial image due to angle or lighting.
