Declaration

TIEVisionObjectsFinder = interface(TIEVisionBase)

Description

An interface to find an object or a set of different objects.
It is possible to load more than one classifier (object detector). Each classifier is executed on a different thread.

Demos

Example

var
  objectsFinder: TIEVisionObjectsFinder;
  rects: TIEVisionVectorRect;
...
// load two face detectors
objectsFinder := IEVisionLib.createObjectsFinder();
objectsFinder.addClassifier('face detector 1', IEVisionLib.createCascadeClassifier(IEVC_FRONTAL_FACE_ALT_TREE));
objectsFinder.addClassifier('face detector 2', IEVisionLib.createCascadeClassifier(IEVC_FRONTAL_FACE_DEFAULT));

// detect objects
objectsFinder.findIn(ImageEnView1.IEBitmap.GetIEVisionImage());

// merge intersecting rectangles of all searched objects
rects := objectsFinder.mergeAllRects();

// Draw rects to image
for i := 0 to rects.size() - 1 do
begin
  with rects.getRect(i) do
  begin
    with ImageEnView1.IEBitmap.Canvas do
    begin
      Pen.Width := 2;
      Pen.Color := clRed;
      Rect( x, y, x + width, y + width );
    end;
  end;
end;
ImageEnView1.Proc.TextOut( Align_Text_Near_Left, Align_Text_Near_Top, Format( 'Found: %d', [ lines.size ]), 'Arial', 12, clYellow, [fsBold] );
ImageEnView1.Update();
