SIFT Saliency Analysis for Matching Repetitive Structures

Algorithm 1

The process of LOOCV test.
Input. An image group of one scene where and . The reference image is .
Select one image as the observation image;
Compute the SIFT feature saliency based on the image training set
according to Section 2;
Perform the feature matching between and ;
If the reference image is matched with all the images from , go to ; else go to ;
Compute the average matching results according to (11)–(13).
Output. The average matching results.
