Declaration
TIEVisionObjectsFinder = interface(TIEVisionBase)
Description
This interface allows you 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.

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();
// loop among rectangles
for i := 0 to rects.size-1 do
begin
ImageEnView1.ObjPenWidth[-1] := 2;
with rects.getRect(i) do
begin
... do something with the rectangle coordinates and size
end;
end;
