摘要
提出了在噪声条件下的一种改进的Canny算子,该算子采用中值滤波代替高斯平滑滤波。实验结果表明改进的canny算子对抑制噪声和保留边缘像素点方面有较好的效果,对图像边缘具有较好的检测精度。
An improved Canny operator is proposed in the noise condition.The operator uses the median value filter instead of Gaussian smoothing filter.Experimental results show that the improved Canny edge operator has better results in suppressing noise and keeping the edge pixels.It has a better detection accuracy on edge.
