Step 5: Place

In this step, TeraStitcher finds an optimal tile placement given the pairwise displacements computed in the previous phases.

The algorithm used by default is based on the minimum spanning tree of the undirected weighted graph constituted by the mesh of tiles connected by edges labeled with the inverse of the displacements reliability measures.

Prerequisites

• an XML descriptor generated by the Threshold step or, alternatively, an XML descriptor in which one (and only one) displacement is stored for each pair of adjacent tiles.

Inputs

• absolute path of the XML descriptor (--projin)

Other inputs (optional)

• output XML descriptor filepath (--projout)
• algorithm (--algorithm)

Output

• XML descriptor saved at --projout containing globally optimal tile positions.

Demo (command line)
