Example

var
  faces: TIEVisionVectorObjRef;
  face: TIEVisionDetectedFace;
  r: TIEVisionRect;
  i: Integer;
begin
  faces := IEVisionLib.createFaceDetector().detect( ImageEnView1.IEBitmap.GetIEVisionImage(), IEVisionRect( 0, 0, 0, 0 ));
  for i := 0 to faces.size() - 1 do
  begin
    face := TIEVisionDetectedFace( faces.getObj( i ));
    r := face.getRect();
    ImageEnView1.LayersAdd( iesRectangle, Rect( r.x, r.y, r.x + r.width, r.y + r.height ), clRed, 2 );
  end;
