Technology recognises people from partial images

 

It has been announced by NEC Corporation that it has developed a ‘Person Re-identification Technology’ that is capable of matching images of people whose figures are partially hidden from cameras, even if the image is taken from behind or from the side.

This technology analyses the entire appearance of a person's photo image, such as their clothes and body shape, to determine whether they match with other images of people. Using the image analysis and deep learning technologies that NEC has cultivated through Facial Recognition Technology and other technologies, NEC was able to establish this high-precision technology that does not rely solely on facial images.

In many cases, Facial Recognition Technology alone may not be enough to match a person whose face is partially concealed. Conventionally, once a person was matched using Facial Recognition Technology, the appearance of that person could then be collected from images taken by multiple cameras. However, when there were many people and objects in an area, such as chairs and counters, people appearing in images of those areas cannot be fully scene, making it difficult to match them.

This technology enables a wide range of people to be recognised, even in places where there are many people or visual obstructions that prevent a person's face or body from being fully seen.

Potential applications for this technology include security support in large-scale facilities with many people or visually blocked areas, as well as assistance in the search for lost children.

"NEC has a large portfolio of world-class biometrics certification technologies that include facial and fingerprint recognition," said Masayuki Mizuno, General Manager, Biometrics Research Laboratories, NEC Corporation. "We are now expanding this portfolio within our NEC Safer Cities solutions, our NeoFace facial recognition AI-engine that boasts the world's No.1 accuracy, and NEC's advanced video analyser."

Main features of this technology include the following:

  1. Even persons who are not fully visible to a camera can be matched: NEC's expertise in deep learning technology is used to match a person's image by automatically selecting other parts of their image when there is overlap between multiple people, such as in crowded or shaded environments where a person's full image cannot be viewed. The matching rate for a person is as high as 90%.
  2. Matching is possible with images taken from behind or from the side: Effective use of deep learning techniques can match people from numerous angles, such as from behind or from the side, and shot with multiple cameras. As a result, this technology can effectively match people using camera images where the face is not visible.
