说明：  实现了DCT的算法，用Matlab实现了任意维图像的DCT变换问题。(DCT algorithm implemented using Matlab implementation of arbitrary-dimensional DCT-image problems.)

说明：   用双线性变换法设计 IIR滤波器 1.了解两种工程上最常用的变换方法：脉冲响应不变法和双线性变换法。 2.掌握双线性变换法设计 IIR 滤波器的原理及具体设计方法，熟悉用双线性设计法设计低 通、带通和高通 IIR 数字滤波器的计算机程序。 (Design by Bilinear transform IIR filter 1. To understand the two most commonly used engineering transformation method: the same impulse response method and the bilinear transform method. 2. Grasp the bilinear transform IIR filter design principles and specific design, familiar with the bilinear design design low pass, band pass and high-pass IIR digital filter computer program.)

The proposed filter is able to suppress high-density of salt-and-pepper noise, at the same time preserving fine image details, edges and textures well.
