Baron_Yam shares a report from Engadget: Police in China are now sporting glasses equipped with facial recognition devices and they're using them to scan train riders and plane passengers for individuals who may be trying to avoid law enforcement or are using fake IDs. So far, police have caught seven people connected to major criminal cases and 26 who were using false IDs while traveling, according to People's Daily. The Wall Street Journal reports that Beijing-based LLVision Technology Co. developed the devices. The company produces wearable video cameras as well and while it sells those to anyone, it's vetting buyers for its facial recognition devices. And, for now, it isn't selling them to consumers. LLVision says that in tests, the system was able to pick out individuals from a database of 10,000 people and it could do so in 100 milliseconds. However, CEO Wu Fei told the Wall Street Journal that in the real world, accuracy would probably drop due to "environmental noise." Additionally, aside from being portable, another difference between these devices and typical facial recognition systems is that the database used for comparing images is contained in a hand-held device rather than the cloud."
