= Stage 1 - Initial Load =

The first stage of building the shape model is to bring in the first set of images and generate landmarks from them.  The following figure illustrates the general process of this stage.

First, the images are imported into the SPC system and converted into the SPC internal format.  Then the alignment of the images is improved.  Next, a set of initial landmarks is generated with a GSD of 120cm at a spacing of 20 degrees.  Batch processing then generates the topography and improves the landmark registration.

The following table details the blocks, the procedures and the programs used to accomplish this stage:
