An example of use a Vision framework for face landmarks detection

First one is face rectangle detection by usingVNDetectFaceRectanglesRequest based on pixelBuffer provided by delegate functioncaptureOutput.

Next we need to setup the propertyinputFaceObservations ofVNDetectFaceLandmarksRequest 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, andrightEyebrow.

To display the results I'm using multipleCAShapeLayer withUIBezierPath.Landmarks detection is working on live front camera preview.
