this program is in java and it can be used to apply various filters to an image.low pass filter,high pass filter,mean filter,median filter can be applied to an image opened using file dialog box

This java applet is a demonstration of digital filters. You should hear a noise waveform when the applet starts up. If you get a message "Need java 2 for sound", then you should get the Java plug-in. The applet starts up with a low-pass filter.

布莱克曼低通滤波器，Blackman bandpass filter-Blackman low-pass filter

菜单功能： 1、高通滤波器（类SignalFilterPassHigh，实现了接口ISignalFilter的所有方法）和低通滤波器（类SignalFilterPassLow，实现了接口ISignalFilter的所有方法）都有滤波功能（接口ISignalFilter定义了滤波器的功能：输入一组整数，滤波后输入另一组整数）。 2、用户选择不同的滤波器，程序生成对应滤波器的接口实例，直接使用接口方法即可。 3、总结接口的作用： (1)规范编程行为，如定义的滤波器的功能。 (2)
