摘　　要：频率域滤波器是图像处理的基本工具,在图像处理领域具有非常广泛的应用,该文采用面向对象抽象工厂设计模式和模板方法模式的方法从滤波算法中抽象出6个实体滤波器类(理想低通滤波器类、理想高通滤波器类、布特沃斯低通滤波器类、布特沃斯高通滤波器类、高斯低通滤波器类、高斯高通滤波器类),2个滤波器抽象类(低通滤波器抽象类,高通滤波器抽象类)和4个工厂类(工厂抽象类、低通滤波器工厂类、低通滤波器工厂类、工厂生成类)。给出所有类之间逻辑关系并画出标准静态结构图。分析各个类中涉及的所有属性和方法,清楚地展示了类之间的数据访问过程。相对于传统的过程化的程序实现方法,基于面向对象的频率域滤波器能够在很大程度上提高各模块的重用性和可扩展性。The frequency domain filter is the fundamental tool of the image processing,which is widely used in the field of image processing.The object⁃oriented abstract factory design pattern and the template method design pattern are used to abstract six categories of entity filters(ideal low⁃pass filter,Ideal high⁃pass filter,Boutworth low⁃pass filter,Boutworth high⁃pass filter,Gaussian low⁃pass filter,Gaussian high⁃pass filter),two abstract categories of filters classes(low⁃pass filter,high⁃pass filter)and four factory categories(factory abstract,low⁃pass filter factory,high⁃pass filter factory,factory producer)from the filtering algorithm.Both of the logical relationship among all categories and the standard static structure diagram are shown,all the attributes and methods involved in each category are analyzed,and the data access process among categories is given clearly.In comparison with the traditional procedural implementation method,the object⁃orient based frequency domain filter can improve the reusability and expansibility of the module to a large extent.
