基于AFM图像的分割方法的研究

he difference between atomic force microscope scanning image and general digital image is that the data represents the height information instead of gray level. According to the characteristics of AFM imges, this paper proposes a watershed segmentation algorithm based on internal tag. Firstly using the LoG filter for filtering and obtains the internal marker by giving a zero threshold to the filtered image, then use the smallest calibration technique to get the external marker image, finally a watershed segmentation algorithm is used to get the final segmentation image. The experimental results show that this algorithm can effectively to segment the AFM image and also avoid to level the image in preprocessing.
