By default, a face landmarks request first locates all faces in the input image, then analyzes each to detect facial features.
If you've already located all the faces in an image, or want to detect landmarks in only a subset of the faces in the image, set the inputFaceObservations property to an array of VNFaceObservationMBS objects representing the faces you want to analyze. (You can either use face observations output by a VNDetectFaceRectanglesRequestMBS or manually create VNFaceObservation instances with the bounding boxes of the faces you want to analyze.)
