Hugin Optimiser tab

As explained on the Hugin Photos tab, hugin uses a photo alignment scheme where it adjusts image orientation and lens settings of source photos until the control points line-up. This process is called optimisation. Normally you will use the Hugin Assistant tab where control points are automatically generated, or use the Feature matching option from the Hugin Photos tab to generate control points.

You can manually create individual control points in the Control Points tab, and you can manage them in both the Photos tab and Control Points table.
