摘要
提出一种改进的Canny算子,其应用动态阈值作为边缘检测的准则,有效地避免了因为用固定阈值进行边缘检测,很可能导致边缘在模糊处丢失等问题。实验中对比Sobel算子和Canny算子,表明改进的Canny算子对于模糊边缘检测效果较好,是一种具有实用价值的边缘检测算法。
The paper proposes an improved Canny operator,which uses the dynamic threshold as the standard of edge detection.The missing blur edge by fixed threshold is avoided by this method.Comparing Sobel with Canny operator,the experiments show that this method gets better result,which has practical value.
