传统Canny边缘算子通过像素点的梯度幅值是否大于梯度方向两侧的像素的梯度幅度值来判定边缘。针对传统Canny边缘算子的判断边缘的方法，分析Canny边缘算子在边缘检测时容易出现边缘点的漏检而造成边缘不连接现象，结合Harris检测算法改进Canny边缘算子来连接断开的边缘并提高检测准确率。实验结果表明，改进的算法检测边缘连接性好并具有更好的检测准确度。

In the classical Canny edge detector ,a pixel is labeled as an edge if its gradient magnitude is lar-ger than those of pixels at both sides in the gradient direction .T he defining edges in this manner causing some obvious missing edges are analyzed .Combined with Harris algorithm ,an improved Canny scheme is then proposed to detect the connected edges and improve the detection accuracy .The experiments show that the edges detected by the improved algorithm are more successive and the detecting results are more accurate .
