摘要
基于分形理论 ,应用计算机数字图像处理技术 ,提出了一种岩相图像识别与分析的新方法。在对典型岩相图像进行图像处理的基础上 ,介绍了岩相轮廓的顺序跟踪识别方法 ,给出了岩相轮廓分形维数的具体计算公式和方法 ,最终得到不同岩相轮廓的分形维数。通过比较不同岩相的分形维数可知 ,同一种岩相轮廓具有比较接近的分形维数 ,而不同岩相分形维数相差较大 ,这说明分形理论可用于岩相图像识别与分析。
Fractal theory has been applied widely to image detecting and analyzing. In this paper, based on fractal theory, lithofacies detecting and analyzing by use of image processing technique were performed. Sequentially tracing method of lithofacies contour was proposed and determination of its fractal dimension was discussed. Fractal dimensions of different lithofacies were obtained. Results show that different lithofacies have obviously different fractal dimensions while same ones have approximately identical fractal dimensions. Thus it is feasible to apply fractal theory to the quantitative analysis of lithofacies in conjunction with digital image processing techniques.
