I have an app that captures frames with the didUpdate callback method.
Each other frame I detect an object and if the object is in the frame (a CVPixelBuffer object) received from the callback, I place a circle in the screen on top of the object.
All works great, with the exception that the CVPixelBuffer and the viewPort have different coordinates (see this SO question: convert-arframes-captured-image-to-uiimage-orientation-issue).
My question is, how to convert only a few points to the viewPort coordinates?
