摘 要: 在分析传统Log边缘检测原理的基础上,针对高斯滤波器尺度因子的选取,引入高斯滤波空间尺度因子计算方法,提出了一种自适应的多尺度Log边缘检测算法,克服了传统Log算法的不足.实验结果表明,改进后的Log算法能有效抑制噪声,并能准确检测图像边缘信息. Based on the analysis of the traditional Log edge detection principle,according to the selection of scale factor for the Gaussian filter,the Gaussian filtering spatial scale factor calculation method is introduced.An adaptive multi-scale Log edge detection algorithm is proposed.The deficiency of the traditional Log algorithm is overcomed.The experimental results show that the improved Log algorithm can restrain noise effectively and detect the edge accurately.
