Zoom_FFT

以下程序是基于matlab软件实现自适应滤波器的lms和rls两种算法，不像有些程序那样冗杂，简练明了。定义一个输入信号加入一组噪音，用自适应算法进行滤波，其中用到一个for循环。(The following procedure is based on the matlab software implementation of the LMS adaptive filter and rls two algorithms, unlike some of the procedures as miscellaneous, concise and clear. The definition of an input signal by adding a group of noise, use of adaptive filtering algorithm, which uses a for cycle.)

repval(X) finds all repeated values for input X, and their attributes. (The input may be vector, matrix, char string, or cell of strings Y=repval(X) returns the repeated values of X [RV, NR, POS, IR]=repval(X) returns the following outputs RV : Repeated Values (sorted) NR : Number of times each RV was repeated POS : Position vector of X of RV entries IR : Index of repetition Example: X=[1 5 5 9 5 5 1] [RV,NR,POS,IR]=repval(X) Output: RV = [1 5] Numbers 1 and 5 are repeated values NR = [2 4] Respectively repeated 2 and 4 times POS = [1 7 2 3 5 6] Position index of X for repeated values IR = [1 1 2 2 2 2] Corresponding to which index of RV )

该代码实现了以2为因子的图像升采样和降采样功能。 降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。 升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。 降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。 图片1.原始图片。 图片2.平滑滤波器降采样&像素点直接复制升采样。 图片3.平滑滤波器降采样&线性插值升采样。 图片4.不使用平滑滤波器降采样&像素点直接复制升采样。 图片5.不使用平滑滤波器降采样&线性插值升采样。 (The code to achieve a 2-factor image upsampling and downsampling function. Down-sampling (with using the averaging filter) and do not use smoothing filter (without using the averaging filter) are two ways to use the smoothing filter. Upsampling including the pixels copied directly (pixel replication method) and linear interpolation (bilinear interpolatoin method) two methods. Down-sampling method and liters a total of four combinations of sampling methods. The program is running, it shows a picture of an original picture and four results. Picture 1 original picture.
