摘　　要：B超图像中存在着大量噪声,传统的边缘检测方法效果都不理想。本文提出将经典的Sobe算子与Canny算子融合检测边缘。实验表明这种方法提取的边缘具有对噪声不敏感、定位精确以及检出的边缘连续等特点。:A lot of noise are contained in ultrasonic image of B- Scan,the conventional edge detection algorithms do not work well. In this paper,a new method which combines Sobel and Canny operator is proposed. The experi ments illustrate that our algorithm is robust and can detect the edge precisely and continuously.
