二维，ＦＤＴＤ，ｐｍｌ，ｍａｔｌａｂ语言。(Two-dimensional, FDTD, pml, matlab language.)

说明：  自己编写的用WSE的方法设计的二维数字滤波器，效果不错。(themselves with WSE prepared by the method of two-dimensional design of digital filters, effectiveness.)

非局部中值滤波 matlab代码,主要用于图像去噪，对于存在周期出现的图像有较好的效果，例如干涉图(Nonlocal median filter matlab code. It is mainly for image denoising and images with the existence of cycles are correspinding to good results, for example interferogram.)

利用双线性Z变换设计巴特沃斯和切比雪夫I型IIR数字滤波器，包括低通、高通、带通、带阻四种形式。使用者只需指定通带、阻带的边缘实际频率及相应的衰减，便可输出数字滤波器 的级联形式的各子系统分子、分母的系数，并输出其幅频和相频响(Bilinear Z transform design Butterworth and Chebyshev Type I IIR digital filters, including low pass, high pass, band pass, band stop four forms. Users simply specify the passband edge frequency stopband actual and corresponding attenuation subsystems can form molecular cascade output digital filter coefficients of the denominator, and the output of its magnitude and phase frequency response)

source code defines the compression approach using dct and jpeg compression approach for the compression of various images. this approach is an lossless compression approach which provides better compression ratio. dct compression in jpeg images.
