#FaceDetector

This is an almost line by line C# port of the swift VisionFaceDetection project for Xamarin.iOS.

In order to run this sample you will need Xamarin.iOS 10.99 + and Xcode 9 +

The original README can be found below, all kudos goes to Pawel Chmiel for authoring this amazing Vision sample.

An example of use a Vision framework for face landmarks detection

First one is face rectangle detection by using VNDetectFaceRectanglesRequest based on pixelBuffer provided by delegate function captureOutput.

Next we need to setup the property inputFaceObservations of VNDetectFaceLandmarksRequest object, to provide the input. Now we are redy to start landmarks detection.

It's possible to detects landmarks like: faceContour, leftEye, rightEye, nose, noseCrest, lips, outerLips, leftEyebrow, and rightEyebrow.

To display the results I'm using multiple CAShapeLayer with UIBezierPath. Landmarks detection is working on live front camera preview.
