| 摘 要： | 传统的亚像素边缘检测都是先粗定位,再进行亚像素细分,因而运行时间较长.采用了一种基于多项式拟合的快速亚像素边缘检测算法.该算法根据图像的灰度分布,运用三次多项式拟合图像的边缘实现亚像素定位,从而达到较高的定位精度.采用在边缘附近取点,进行亚像素边缘检测,减少了运行时间.仿真实验给出的实验结果证明了该算法的有效性.

| Abstract: | Since traditional edge detection algorithms have the disadvantages of low precision and efficiency in measuring the edge,a sub-pixel edge detection algorithm based on the polynomial fittings is proposed.According to the grey level distribution of the picture,this algorithm uses cubic polynomial to fit the edges to realize sub-pixel localization.Traditional sub-pixel edge detection algorithms detect coarse position at first,and then carry out the sub-divide,therefore the running time is relatively long.This ... |
