| 摘 要： | 提出一种基于模糊梯度思想的微齿轮图像边缘检测算法.该算法采用正切归一化函数对灰度图像模糊化,并计算该模糊图像的梯度矩阵;采用正弦函数对梯度矩阵进一步模糊化得到模糊梯度矩阵;采用基于归一化实数编码的遗传算法来搜索最优的阈值λ对模糊梯度矩阵做截集,获取图像边缘点集合.实验中以不同微齿轮图像作为实验对象,测试了该算法性能.实验结果表明,该算法的检测精度优于10μs,检测时间基本为1s,整体性能优于Canny算法和Pal-King算法.

| Abstract: | A new image edge detection algorithm which is based on the theory of fuzzy gradient is proposed in the paper.The steps of the algorithm is as follows:firstly,the original gray image is changed into fuzzy matrix by the normalized tangent function;secondly,gradient matrix of the fuzzy matrix mentioned above is computed;thirdly,the fuzzy gradient matrix which is also called fuzzy set of the gradient matrix is obtained using sine function;and in the end,appropriate threshold which is identified by genetic algor... |
