TIEBitmapHelper.DetectPeople

Declaration

function DetectPeople(): TIERectArray;

Description

A shortcut method that creates a TIEVisionPeopleDetector object and calls detect.



Note:
◼ You must add the iexHelperFunctions unit to your uses clause
◼ You can draw the rects to a canvas using DrawRects
◼ Object detection requires IEVision. You will need to register it before calling the method

Method Behaviour

The following call:

rects := ImageEnView1.IEBitmap.DetectPeople();

Is the same as calling:

peopleDetector := IEVisionLib.createPeopleDetector();
vrects := peopleDetector.detect( ImageEnView1.IEBitmap.GetIEVisionImage() );

Demo

Example

// Detect people in image
rects := ImageEnView1.IEBitmap.DetectPeople();
// Draw rects to image
for i := 0 to Length(rects) - 1 do
begin
  r := rects[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;
ImageEnView1.Proc.TextOut( Align_Text_Near_Left, Align_Text_Near_Top, Format( 'Found: %d', [ Length(rects) ]), 'Arial', 12, Text_Color, [fsBold] );
ImageEnView1.Update();
