Emotion recognition – up next for surveillance?
In a recent surveillance tech expo held in Shenzhen,
China, it seems emotion recognition in surveillance was the hot topic that resulted from the event.
The technology trend looks set to be particularly prevalent in the travel
sector, being rolled out at airports and subway stations.
Facial recognition has certainly become a more focused
topic in the public sphere over recent years – not just in the security sector.
Though, while the benefits in security and safety are numerous, concerns over
private data security are never far from the surface. Blurring technology is
one method that many software companies appear to be using, in order to
overcome these concerns.
Other problems include the sophistication of the
technology and whether it is reliable enough, as facial recognition cameras
work often work best at eye level, so the camera can effectively ascertain and
assess the specific distances between points of the face, in order to match
this to its data.
Emotion recognition
Emotion recognition would, presumably, be taking things a
step further. Some of the world’s largest companies are reportedly developing
the technology, but commentators suggest it isn’t yet at a stage to be
completely utilised reliably.
The idea behind emotion recognition for the security
sector is likely to mean that cameras will be able to automatically recognise
signs of stress and nervousness, as well as other common signs of unscrupulous
activity. In western China, the technology is currently being deployed at
customs, in a bid to prevent illegal acts of terrorism and smuggling, says
authorities.
While it doesn’t appear quite ready for full commercial
use, reports indicate it was clearly a hot topic at the expo and as examples of
use continue to develop, it will certainly be interesting to see where emotion
recognition technology goes
