一种固定阈值的毫米波图像边缘检测方法

文章提出了一种固定阈值的毫米波图像边缘检测方法。根据图像的统计特征确定出像素的标准梯度强度，并采用单阈值对图像进行边缘粗定位，然后施行非最大抑制处理和滤波，得到最终检测结果。由于该算法对各幅毫米波图像设置相同的阈值，故能实现自动检测，同时还具有计算量小的特点。实验结果表明该方法进行毫米波图像边缘检测的有效性和可行性。

A Fixed Threshold Edge Detection Approach for Millimeter Wave Images

This paper proposes a fixed threshold edge detection scheme for millimeter wave image. The standardized gradient magnitude is introduced to determine the edges primarily, then the non-maximum suppression phase is used to get specific edges. Since this scheme adopts a fixed and single threshold for each millimeter images it can be implemented automatically. In addition, its computational complexity is small. Theory analysis and experiments demonstrate that it is an effective and feasible edge detector for millimeter images.
