摘要
本文利用数学形态学中的开运算构成了一类形态带通滤波器，并且深入地分析了它们的性质，这类滤波器只允许图象中具有特定形状的物体通过。因而能够有效地用于抽取图象的形状特征。
In this paper,a class of morphological bandpass filters is constructed by using morphological opening,and its properties are investigated in detail.These filters allow only the image objects with specific shape to pass through them,so that they can be effectively applied to image shape feature extraction.
