Demo

Example

// Create our tracking object
m_objectTracker := IEVisionLib.createObjectTracker();

// Specify the object to track
ImageEnView1.IEBitmap.Origin := ieboTOPLEFT;
image := IEVisionLib.createImage(ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height, ievUINT8, 3, ImageEnView1.IEBitmap.Rowlen, ImageEnView1.IEBitmap.ScanLine[0]);
with ImageEnView1 do
  m_objectTracker.setInitialPosition(image, IEVisionRect(SelX1, SelY1, SelX2 - SelX1, SelY2 - SelY1));

// As video frame changes, locate new position of the object
rotRect := m_objectTracker.locateNewPosition(ImageEnView1.IEBitmap.GetIEVisionImage().flip(ievY_AXIS), backProj);
... Show rotRect, e.g. with a rectangular shape layer
