数学形态学图象处理方法正在成为图象领域中的一门新技术,它通过改变图象中目标物的空间分布形式或结构状态达到图象增强的目的,具有较大的应用前景。本文介绍了二种基本数学形态学运算一膨胀与收缩的基本概念、运算过程及程序设计方法,并举例说明了膨胀,收缩技术及由它们引伸而来的递归运算和组合运算一断开、闭合技术在地质、物化探、遥感等多种地学数据综合图象处理中的应用效果。 The mathematical morphological image processing method is becoming a new technology in the field of image. It has great application prospect by changing the spatial distribution or structural state of the object in the image to achieve image enhancement. This paper introduces two basic mathematical morphology operations expansion and contraction of the basic concepts, computing processes and programming methods, and an example of expansion and contraction techniques derived from them derived from the recursive operations and the combination of a disconnect, closed Technology in geology, geophysical and geochemical exploration, remote sensing and other geosciences data integrated image processing application effect.
