* This example program shows the use of pattern matching with shape models
* to locate an object.  Furthermore, it shows how to use the detected position
* and rotation of the object to construct search spaces for inspection tasks.
* In this particular example, the print on an IC is used to find the IC.  From the
* found position and rotation, two measurement rectangles are constructed to
* measure the spacing between the leads of the IC.  Because of the lighting
* used in this example, the leads have the saturated gray value of 255 at several
* positions and rotations, which enlarges the apparent width of the leads, and
* hence seems to reduce the spacing between the leads, although the same
* board is used in all images.
