基于高斯滤波器的尺度相乘边缘检测算法

Edge Detection by Scale Multiplication Based on Gaussian Filter

论文提出一种基于高斯滤波器的尺度相乘边缘检测算法。该算法用两个不同尺度参数的高斯滤波器分别对图像进行滤波平滑,然后将所得的两个结果相乘后,再利用Canny算子对图像进行边缘检测。该算法具有算法简单、编程容易、计算量小等特点。论文最后通过实验验证了该算法能较好地抑制噪声干扰和有较高的边缘定位精度。

This paper presents an algorithm to edge detection by scale multiplication based on Gaussian filter.The algorithm uses Gaussian filter with two different scale factors to process the image respectively.Then the two results multiply and the Canny operator is used to detect the image edge.It is shown that this algorithm is simple,easy to program and has lower computational burden.Experimental result shows that it not only has good detection in edge localization,but also can suppress the noise well.
