摘要
使用带衰减因子的Sobel算子对图像进行边缘检测,得到高亮显示的粗边缘,然后再次用Sobel算子二次检测图像,以2次所得图像的差作为细化结果,并结合图像分割算法确定阈值对图像进行二值化处理。
The thick and bright edge is obtained in Sobel edge -detection, the new image also can be processed using Sobel operator,then a mid- image appeared. A third - image can be obtained by subtracting mid - image from third - images an efficient image threshold selection method is necessary during the process.
