Class BatchSimilarityGroundTruth

java.lang.Object

cz.fidentis.analyst.gui.app.tools.BatchSimilarityGroundTruth

public class BatchSimilarityGroundTruth
extends Object

A class for testing the efficiency of batch processing algorithms. The goal of this tool is to create a "ground truth" measurements for other optimization techniques

• All pairs of faces are taken one by one from the collection.
• ICP registration is performed for each pair, but only in one direction (the second to the first)
• Hausdorff distance for each pair is computed in both direction (A-B and B-A). HD uses POINT_TO_POINT strategy and absolute distances.

Stats for 100 faces WITH CROP:

 ICP computation time: 02:27:32,170
 HD computation time: 02:08:34,001
 Total computation time: 05:29:55,321
 

Stats for 100 faces WITHOUT CROP:

 ICP computation time: 02:23:06,495
 HD computation time: 01:59:55,520
 Total computation time: 05:16:46,154
