摘要
针对Harris算法中存在的角点定位不精确,高斯平滑窗口大小不易选择等问题,提出了一种改进算法,利用B样条函数来代替算法中的高斯平滑函数,可避免高斯窗口的选择,并提高角点的定位精度.通过实验对改进算法的性能进行了分析,证明改进算法能够有效提高角点定位精度.
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.
