In SURF algorithm, original process for feature point's main orientation assignment is not optimized. It uses a sliding window covering an angle with 60 degrees shift around circle region, and calculates the sums of all Haar responses to yield vector in it. Along rotating, many overlap regions generated. Therefore, lot summations need be repeatedly taken. So speed slow. An algorithm fast calculating was proposed. wiped off repeated regions, were just needed computed once, which only...
