| 摘 要： | 针对传统的Canny算法在平滑滤波时对图像边缘检测的影响,以及需要预先设定高低阈值等缺点,本文提出了一种新的Canny边缘检测算法。首先采用自适应中值滤波对图像进行处理;其次,添加45°和135°方向的梯度模板来计算梯度幅值;最后,采用Otsu算法计算经梯度幅值运算得到图像的高低阈值。实验结果表明,该改进的Canny算法具有良好的抗噪性能,并且能精确的检测出边缘信息。

| Abstract: | A new adaptive Canny operator is proposed which aimed the image edge areas effect when traditional Canny operator under Gaussian smooth and the shortcomings of threshold level pre-set. Firstly, the adaptive median filtering is adopted to process it; secondly, adding the 45° and 135° direction of gradient template to calculate gradient amplitude; finally, using the Otsu algorithm to calculate the gradient amplitude operation get images of high and low threshold value. The experiment results show that the improved Canny algorithm has good anti-noise performance, and can accurately detect the edge information. |
