Zalivin, Singular Point Comparisons During Panoramic Image Formation, International Journal of Soft Computing, Volume 10,Issue 6, 2015, Pages 454-457, ISSN 1816-9503, ijscomp.2015.454.457, (https://makhillpublications.co/view-article.php?doi=ijscomp.2015.454.457) Abstract: In this study, the review of the most common methods of critical point comparison are analyzed during the solution of various problems of image processing such as, the formation of panoramic images. The order of singular point descriptor obtaining is analyzed, the main types of singular points are revealed and the property characteristics are described obtained by descriptor construction with which may assess their effectiveness. The descriptions of the following descriptors are presented: SIFT, PCA-SIFT, SURF, GLOH, DAISY, BRIEF. The principles and features of their research are described.
