基于Canny算子的改进的图像边缘检测方法

Improved Edge Detection Algorithm Based on Canny Operator

针对Canny算子的边缘检测算法提出了自己的改进方法,用MTM滤波算法取代Gauss滤波方法,并对算法中的参数选取进行了讨论。实验结果表明,改进的算法有效地提高了边缘检测准确性,极大地降低了计算量,取得较好的效果。

In this paper, an improved edge detection algorithm based on Canny operator is proposed in which Gauss filter is replaced by MTM filter. Then the parameters in the algorithm are studied. Experiment shows that the veracity of edge detection is improved evidently, calculating quantity is reduced enormously, and a preferable result is obtained.
