Then a new kind of edgedetectionoperator was used to obtain edges from the enhanced image.
最后利用迭代算法对边缘图像进行二值分割。对改进的模糊边缘检测算法进行了实验。
2
Discusses and compares various edgedetection operators for digital image processing, and analyses the characteristics of each operator.
讨论和比较数字图像处理的几种丝缘检测算子，分析各算子的特点。
3
Sensitivity is different for different differential operators, how to choose a suitable edgedetectionoperator to obtain exact information of edge, is the essential step for fracture surface image.
