How-Old.net is the demo site of Microsoft's Project Oxford, a cloud-based algorithm that guesses the age of humans based on facial recognition. With Face APIs, developers can experiment face detection, face verification, similar face searching, face grouping, and face identification which detects gender and age. Along with Face API, Project Oxford has released Speech API and Computer Vision API also in beta stages. The fourth API, Language Understanding Intelligent Service (LUIS), is available by invite.
