Description: 数字信号处理的应用之一是从含有加性噪声的信号中去除噪声。现有被噪声污染的信号x[k]=s[k]+d[k],式中：为原始信号d[k]为均匀分布的白噪声。（1）分别产生50点的序列s[k]和白噪声序列d[k],将二者叠加生成x[k],并在同一张图上绘出x0[k],d[k]和x[k]的序列波形。（2）均值滤波可以有效去除叠加在低频信号上的噪声。已知3点滑动平均数字滤波器的单位脉冲响应为h[k]=[1,1,1 k=0,1,2],计算y[k]=x[k]*h[k],在同一张图上绘出前50点y[k],s[k]和x[k]的波形，比较序列y[k]和s[k]。 -digital signal processing applications from one containing additive noise signal denoising. Existing noise pollution was a signal x [k] = s [k] d [k], where : of the original signal d [k] uniform distribution of white noise. (1) have 50 points each sequence s [k] and white noise sequence d [k] superposition of the two generation x [k] and the same is likely to draw a map x0 [k] d [k] and x [k] waveform sequence. (2) mean filter can effectively remove superimposed on the low-frequency noise on the signal. 3:00 known moving average digital filter unit for pulse response h [k] = [k = 0,1,2 1,1,1] Calculation y [k] = x [k]* h [k], the same is likely to draw a map before 50 y [k] s [k] and x [k] waveform sequence comparison y [k] s and [k].

[matlab] waveletentropy

Description: 求解一维心电图的小波熵，主要用来计算小波熵，但是这个并没有去掉明显的噪声，除去噪声的话，请把i＝1改为2-electrocardiogram for a peacekeeping wavelet entropy, mainly used to calculate the wavelet entropy, However, this does not remove the obvious noise, remove noise, then please send i = 1 to 2

[Graph Recognize] NoiseReduction_v1

Description: 本程式实做了Noise Reductin Algorithm 2005年一个韩国人在ieee发表的Paper Block-based noise estimation using adaptive Gaussian filtering 此论文也收录在资料夹中，供使用者参考。首先，click open file，选择第一张原始图(未被杂讯污染) 接下来选择第二张图(有杂讯) 你可以直接点选Noise Reduction观看结果也可以先调整旁边的threshold，观看不同threshold下去除杂讯的效果。本程式利用统计理论，在去除杂讯的过程，成功保留了边缘特征，使影像看起来较为立体、清晰。-This program is to do a Noise Reductin Algorithm2005 a Korean in the year ieee published PaperBlock-based noise estimation using adaptive Gaussian filtering of this thesis is also included in the folder for reference. First of all, click open file, select first the original plan (not noise pollution) Next select the second graph (with noise) you can watch the results of Click Noise Reduction can also adjust next threshold, watch different under the threshold to remove noise effects. This program using statistical theory, to remove noise in the process of successfully retained the edge features, to make images look more three-dimensional and clear.

[AI-NN-PR] AdaptiveLineEnhancer

Description: This demonstration illustrates the application of adaptive filters to signal separation using a structure called an adaptive line enhancer (ALE). In adaptive line enhancement, a measured signal x(n) contains two signals, an unknown signal of interest v(n), and a nearly-periodic noise signal eta(n). The goal is to remove the noise signal from the measured signal to obtain the signal of interest.

[ARM-PowerPC-ColdFire-MIPS] contraharmonic

Description: this file contains the implementation of the "contraharmonic filter" using the basic formula of finding contraharmonic mean achieved through the use of for loops. contraharmonic filter can remove both -SALT n PEPPER noise from the image but not simultaneously. The positive order contraharmonic filter removes the pepper noise and the negative order removes the salt noise. SALT n PEPPER noise has been added to the image and it has been removed sequentially using the contraharmonic filter of positive and negative filters one after the other. It has been observed that the removal of salt noise followed by the removal of the pepper noise gives better results-this file contains the implementation of the "contraharmonic filter" using the basic formula of finding contraharmonic mean achieved through the use of for loops. contraharmonic filter can remove both-SALT n PEPPER noise from the image but not simultaneously.
