对原始灰度图像进行图像压缩，对此图进行 8×8 DCT 变换后，分别只保留 DC系数，以及保留前 4、8、16 个变换系数(DC＋AC) ，然后再分别进行 IDCT 变换 (The original gray image compression, this map for 8 × 8 DCT transform, respectively, to retain only the DC coefficient, and to retain the former 4,8,16 months transform coefficients (DC+ AC), and then separately IDCT transform)

图像分形盒维数的算法源程序.此算法是基于黑白二值图像的，因此，需要对导入的图片进行二值化处理，因此算法存在一定误差，但是此算法误差控制在4 以内(Image fractal dimension algorithm source code box This algorithm is based on black and white binary image, and therefore, need to import the picture binarization processing, so the algorithm there are some errors, but this algorithm is less than 4 error control)

FIR滤波器中汉宁窗和布莱克曼窗幅频特性曲线和相频特性曲线对比(FIR filter Hanning window and Blackman window of amplitude-frequency curve and phase frequency response curve compared)

AR自适应滤波器，用Kalman滤波器跟踪AR模型的吸收变化(adaptive AR model，use kalman filter to trace the variance of ar coeffience)

将输入d进行扩张，方法是在d的每个数据中插入M-1个零值。 如输入d=[1,2,3,4] M=3 输出out=[1 0 0 2 0 0 3 0 0 4 0 0](To expand the input d, the method is to insert each data d, M-1 zero value. If the input d = [1,2,3,4] M = 3 output out = [1 0 0 2 0 0 3 0 0 4 0 0])
