Facial Recognition

I spotted this very interesting article, about recent improvements in machine vision for facial recognition.

The main point made in the article is that it is much easier for automated systems to recognise objects in 3D, rather than from 2D images. It appears that standard (stereo?) cameras would largely be intended to perform the task of data capture, which sounds hopeful for a low cost solution - rather than expensive laser scanners for instance.

Of course there is a major use for this type of technology for surveillance and 'big brother' style intelligence, along with various privacy issues associated with automatically tracking people through CCTV. However, for a domestic or commercial autonomous mobile robot performing everyday tasks, reliable face recognition, as well as general object recognition are quite key to success. The image processing could even be off-board the robot, perhaps - as mentioned in the article, using IP web cams to capture the image data over a wired or wireless network.

Discuss this article on the forums. (1 posts)
