| Abstract: | In order to improve the shortage of imprecise location and difficult determination of the size of Gaussian Windows of Harris corner detection algorithm, an improved Harris corner detection algorithm is proposed by using the B spline funcion instead of Gaussian Window. It can avoid the choice of a Gaussian window and improve the positioning accuracy of the corner. The performance of the improved algorithm is analyzed by the experiment, which proves that the improved algorithm can improve the positioning accuracy of corners effectively. |
