public class PairwiseDistanceTask
extends BatchDistanceTask

A task that computes similarity of a set of faces by applying two-way (from A to B and vice versa) distance measurement to all pairs A and B if the set. The average face, if exists, is skipped from the similarity measurement (i.e., we do not measure its distance to other faces). The exact computation parameters are taken from the BatchDistancePanel.

Constructor Details

PairwiseDistanceTask

public PairwiseDistanceTask(ProgressDialog<Void,Integer> progressDialog,
 BatchDistancePanel controlPanel,
 boolean crop)

Constructor.

Parameters:

progressDialog - A window that show the progress of the computation. Must not be null

controlPanel - A control panel with computation parameters. Must not be null

crop - If true, then the measured faces are auto-cropped to the surface of the average face. This option slows down the computation even more, but enables us to compare the results of this pairwise comparison other methods based of indirect measurement (i.e., the methods that use the average face as a "gauge"). This option is ignored if there is average face computed.

Method Details

doInBackground

protected Void doInBackground()
                       throws Exception

Specified by:

doInBackground in class SwingWorker<Void,Integer>

Throws:

Exception

printTimeStats

protected void printTimeStats()

numCycles

protected double numCycles(int nFaces)

setDistValues

protected void setDistValues(int i,
 int j,
 MeshDistanceVisitor pairwiseVisitor,
 MeshDistanceVisitor meanFaceVisitor)

Sets an average distance and a sample standard deviation but only considering vertices that are not copped either by the second face in the pairwise comparison or the mean face (if defined).

Parameters:

i - the first index

j - the second index

pairwiseVisitor - distance visitor

meanFaceVisitor - mean face visitor
