Looking at someone’s face can tell you a lot about who they are. Running a picture through Face.com‘s systems let’s you turn those instincts into cold hard data. The Israel-based company has made a name for itself over the past few years by providing some of the best facial recognition technology available on the web. To date, developers all over the world have used their API to find nearly 41 billion faces! More than just detecting and identifying faces, the Face.com API provides all sorts of great data: gender, presence of a smile, approximate mood, etc. The latest innovation? Face.com can now accurately estimate the age of the faces it sees. Singularity Hub spoke with CEO and Co-Founder Gil Hirsch about the new Age Detection feature, the success the company has enjoyed so far, and the future of facial recognition technology.
