Geometric voting algorithm for star trackers

Michael Kolomenkin, Sharon Pollak, Ilan Shimshoni, Michael Lindenbaum
2008 IEEE Transactions on Aerospace and Electronic Systems  
The algorithm is based on a geometric voting scheme in which a pair of stars in the catalogue votes for a pair of stars in the image if the angular distance between the stars of both pairs is similar.  ...  As angular distance is a symmetric relationship, each of the two catalogue stars votes for each of the image stars.  ...  The algorithm is based on a geometric voting scheme in which a pair of stars in the catalogue votes for a pair of stars in the image if the angular distance between the stars of both pairs is similar.  ...
