TIEVisionObjectsFinder.findIn

Declaration

procedure findIn(image: TIEVisionImage); safecall;

Description

Loops among all added classifiers to find objects inside the specified image.
Objects found are returned by getFoundRectCount and getFoundRect, or with mergeAllRects.

Parameter	Description
image	Image where to find the objects

Example

// Find Faces in image
objectsFinder := IEVisionLib.createObjectsFinder();
objectsFinder.addClassifier('face detector 1', IEVisionLib.createCascadeClassifier(IEVC_FRONTAL_FACE_DEFAULT));
objectsFinder.addClassifier('face detector 2', IEVisionLib.createCascadeClassifier(IEVC_FRONTAL_FACE_ALT_TREE));
objectsFinder.addClassifier('face detector 3', IEVisionLib.createCascadeClassifier(IEVC_FRONTAL_FACE_ALT));
objectsFinder.addClassifier('face detector 4', IEVisionLib.createCascadeClassifier(IEVC_FRONTAL_FACE_ALT_2));
objectsFinder.addClassifier('face detector 5', IEVisionLib.createCascadeClassifier(IEVC_PROFILE_FACE));
objectsFinder.findIn(ImageEnView1.IEBitmap.GetIEVisionImage());
rects := objectsFinder.mergeAllRects(); // merge intersecting rectangles
// Draw rects to image
for i := 0 to rects.size() - 1 do
begin
  r := rects.getRect(i);

  with ImageEnView1.IEBitmap.Canvas do
  begin
    Pen.Width := 2;
    Pen.Color := clRed;
    Brush.Style := bsClear;
    Rectangle( r.x, r.y, r.x + r.width, r.y + r.width );
  end;
end;
