face recognition to detect mood

Question

I'm looking for a specific form of facial recognition. I want to detect he mood of face in a given image, e.g. whether it is smiling or sad. Are there any .NET libraries for this?

Answer 1

You should take a look at face.com, it is a popular face recognition API. You can read a tutorial about using it with C# here. You can detect happy / sad via the mood API.
