Mango brings you the possibility to use your application to get the live image from camera. This has brought many new options to people interested in augmented reality and for applying all sorts of filters straightforward. I personally find the use for face recognition very exciting and interesting. Unfortunately, you cannot use OpenCV library (actually, the wrapper for .NET called EmguCV). Fortunately there are people who write software on Codeplex. In this article I will use FaceLight, a project for face recognition in Silverlight, created by René Schulte, and create a Windows Phone application that can recognizes faces on camera. --Igor Ralić
