| 摘 要： | 针对石油勘探中的岩芯识别问题,给出了一种分形理论和纹理分析相结合的识别算法。算法首先使用"双毯法"计算岩芯图像的分形维数,根据分形维数对岩芯图像进行分组,使具有相似分形维数的岩芯图像分为一组,并提取出图像的特征区域,实现对岩芯图像的"粗分"。其次对分组中的岩芯图像使用"空间灰度层共现矩阵法"进行"细分",实现岩芯图像的识别。实验结果表明给出的算法能够实现对岩芯图像的有效识别。

| Abstract: | For the problem of core identification in petroleum explorations, an algorithm was presented which combined fractal theory and texture analysis.Firstly it computed the fractal dimensions of the core images using double blanket method, according the fractal dimensions,it can make those have approximations of fraetal dimensions in one group, and extract the characteristic area, so realized the rough segmentation.Secondly,to those in one group,it used the method of spatial gray level co-occurrence matrix to realize subdivision.Experimental results showed the proposed algrithm can realize the identification of core images effectively. |
