Sample project for FaceDetection + CoreImage
This sample is based on this tutorial which shows the usage of
CIDetector class, pretty straight forward :)
The aim of this sample is to show the right way to convert coordinates (CoreImage → UIKit) which is not a big deal but the former example does it incorrectly and it seems to have gained some popularity already.
This my (another) one cent to the dev community … blah blah blah.
Hope it helps.
