Microsoft facial recognition tool is no longer able to read emotions

Microsoft is retiring a controversial facial recognition feature that claims to identify emotion in people's faces from videos and photos. As part of an overhaul its AI policies, the US tech giant is removing facial analysis capabilities that infer emotional states, like surprise and anger, from Azure Face. It's also retiring the ability of the technology platform to identify attributes such as gender, age, smile, hair and makeup. Microsoft's Azure Face is a service for developers that uses AI algorithms to detect, recognise, and analyse human faces in digital images. It is used in scenarios such as identity verification, touchless access control and face blurring for privacy.
