Statistics Menu

This menu has a number of options for performing statistical and related operations.

Average construction

Match to base face ::

This is a legacy function used to align surface via delineation of the 2D texture map using a .tem file. Recommended to use the warping options on the Edit menu instead.

Display N::

Displays the number of faces in this averge on the status line (at the bottom of the window).

Add to average::

Prompts for a .obj file to add to the currently displayed (average) surface. Files should have the same mesh structure before calling this method, use Edit->Warp3D.

Average list::

Average a set of .obj files together. The list is read from a text file with the name of each (aligned) .obj file on each line.

Iterate average::

Tick this option when averaging lists of faces for improved accuracy of the average. The shape of the average is affected by the (rigid+scale) alignment of the faces, for best results faces to be averaged should be aligned to the average. As the average is initially unknown this iterates by aligning to the current estimate of the average each iteration.

Auto procrustes normalise::

Procrustes normalisation is rigid body plus scaling to minimise the differences between surfaces. This option should be turned on unless the surface position/orientation/scale are pre-normalised some how.
