I'm looking for a specific form of facial recognition. I want to detect where all the faces are located (and that's all) on an image of students in a class-picture.
So in other words, I'm not trying to compare two faces and see if they match either.
How can I do this in C#? I can't seem to find any open-source projects on NuGet regarding this, and I've looked on CodePlex too.
Now that Face has retired since it was purchased by Facebook, I use Sky Biometry, which has a C# .NET API and is free.
It's cloud based and obviously requires an Internet connection, but who cares.
