摘要
简述了最大类间方差法的方法原理,并分别使用迭代阈值分割法、最大类间方差法及模糊C均值聚类算法,对最接近FMI图像中溶孔的高斯峰图片进行了分割和分析;介绍了蚁群优化的最大类间方差法的方法原理,并使用该方法对一段溶蚀孔洞型储层的FMI成像测井图像进行了分割。实践证明,利用蚁群优化的最大类间方差法能很好地分割出包含裂缝、孔洞的子图像,且分割效率有了一定的提高,为后续的参数定量计算打下了基础。
This paper described the basic principles of OTSU algorithm, segmented the image that created by simulate function with iterative algorithm, OTSU algorithm, and fuzzy C-means clustering algorithm respectively, and analyzed the reasons. We introduced the basic principles of OTSU algorithm optimized by ant colony, and segmented the FMI logging image of a dissolved cavity reservoir. It is concluded that the OTSU algorithm optimized by ant colony can segment the sub-image of the fracture, emposieu and cave, and the efficiency is improved, which provides a very good foundation for the further quantitative calculation.
