This paper presents a fast convex hull algorithm for a large point set. The algorithm imitates the procedure of human visual attention derived in a psychological experiment. The merit of human visual attention is to neglect most inner points directly. The proposed algorithm achieves a significant saving in time and space in comparison with the two best convex hull algorithms mentioned in a latest review proposed by Chadnov and Skvortsov in 2004. Furthermore, we propose to use an affine transformation to solve the narrow shape problem for computing the convex hull faster. 相似文献
