| 摘 要： | 针对传统单一算子图像边缘检测效果欠佳的问题,提出一种新的边缘检测算法.新算法融合了LOG算子对于图像的阶跃型边缘定位准确、旋转不变性的优点和Canny算子的强抗噪声能力.通过实例实验分析表明:相比传统单一算子,新算法检测图像边缘的准确度更高,检测效果更理想.

| Abstract: | A new algorithm is proposed according to tradilional single operator is ineffective in image edge de tection. The new algorithms blend the advantages of LOG operator to detect step edgc positioning accuracy and rotational invariance with the advantages of Canny operator with strong noise immunity. An example ex- perimental analysis showed that the new algorithm detect edges higher accuracy and better effect than traditional single operator. |
