SIFT Saliency Analysis for Matching Repetitive Structures

Algorithm 2

The experimental procedure of the quality computation.
Input. All the matching pairs of each scene for the LOOCV test.
Set a strict threshold for each method as stated in Section 3.1 to find the robust seeds of each matching pair;
Determine the minimum number of the seeds among all the methods;
If there is a method finding more seeds than the minimum number, go to; else, go to ;
Sort the seeds based on their similarity values which are computed according to the Equation (5) and (7)
in an ascending order;
Select the determined number of the seeds from the top-ranked sequence determined in step ;
Compute the , and of the seeds for each method according to (11) (13);
If the quality computation in step for all the matching pairs is finished, go to ; else go to ;
Compute the average quality of the seeds for each scene.
Output. The average quality results for the seeds of each scene.
