After you specify control point pairs, you must save them in
the MATLAB® workspace to make them available for the next step
in image registration, processing by
To save control points to the MATLAB workspace,
Select File on the Control Point Selection Tool menu bar.
Choose the Export Points to Workspace option. The Control Point Selection Tool displays this dialog box:
By default, the Control Point Selection Tool saves the x-coordinates
and y-coordinates that specify the locations
of the control points you selected in two arrays named
although you can specify other names. These are n-by-2
arrays, where n is the number of valid control
point pairs you selected. This example shows the
containing four pairs of control points. The values in the left column
represent the x-coordinates; the values in the
right column represent the y-coordinates.
