Finally a novel algorithm flow is made to achieve 3d focusing with zoom microscope . for low enlargement images , global - coarse orientation is realized with auto - thresholding , corrosion - inflation operation and connected components labeling . and for large enlargement images , local - precise orientation is achieved by multiresolution wavelets segmentation on focus measure technique , which use the phenomena that images blur when out - of - focus
对于低放大倍数下的全局图像,主要利用形态学中的腐蚀膨胀操作、自动阈值分割、区域标记等技术完成了键合目标中心位置的粗定位;而对于高放大倍数下的局部图像,根据其半离焦的特征利用基于小波高频能量的多尺度显微图像分割方法实现了精定位。
