Abstract分析了基于梯度的边缘检测算法,针对其在参数确定自主能力不高的问题,提出一种新的基于大津法和统计理论的自适应边缘提取方法,通过对一组参数进行统计优化,自适应地确定边缘检测的全局最优参数,最后,采用Canny边缘检测算子对本算法进行验证.实验结果表明,本文提出的非结构环境下目标自适应边缘提取方法能够有效地抑制噪声,自适应地确定图像最优边缘参数,提高了边缘定位精度。
Other AbstractStudies of edge detect algorithms based on grads are carried out in this paper first, and for the sake of improving the ability of parameters selection adaptively, a new method of automatic selection of edge detector parameters based on algorithm of OSTU and statistical theory is presented. The global optimized parameters are determined automatically and adaptively through an optimized method of statistics, finally, Canny edge detector is used to prove the validity of our method presented in this paper. Some experiments are carried out and the results show that the method in this paper could reduce the noise affectively, select the optimized parameters automatically and adaptively, improve the precision of edge detection, especially in application of unstructured environments without the pre-information.
