| 摘 要： | 因传统Canny算子在图像边缘检测应用中无法取得理想效果，故提出利用有较好抑制噪声作用的FFT，实现增强图像的功能，再采用传统的Canny算子，提取原始图像边缘的方法，算法综合了两者的优点．实验结果表明，采用改进算法有效地增强了边缘检测的准确性，取得了比较理想的边缘检测效果．

| Abstract: | As traditional Canny operator for edge detection of image can not achieve desired results, an FFT is proposed with better noise inhibition to enhance image. And then the traditional Canny operator is used to extract edge information from the original image. The algorithm combines the advantages of two algorithms. Experiments show that the improved algorithm can effectively improve the accuracy for edge detection, and obtains the desired results of edge detection. |
