该文件使用FIR滤波器滤除采集的心电信号中的工频干扰，实测滤波效果不错，不过并不能处理基线漂移。文件中提供了滤波器的定点系数。(The file uses the FIR filter to remove the collected ECG frequency interference, measured the filtering effect is good, but does not deal with the baseline drift. Document provides a fixed filter coefficients.)

利用matlab自带的fisheriris数据集（为了可视化将其看成两类）（setosa类和非setosa类）测试svm(test the svmtrain and svmslassify functions by the fisheriris by the matlab software)

说明：  在二维平面内生成随机点并构造二维Voronoi图(Construction of 2D Voronoi diagram with random points)

能够非常清楚的看出幅值和时间的变化规律，不用再画时、频图(Can very clear indication of the amplitude and the change of time rule，Don t draw, frequency chart)

Fuzzy knowledge-based system identification and modeling process is composed of two parts: variable identification and parameter identification. In variable identification, the significant variables of the system are identified among the set of possible variables. In parameter identification, the parameters of the knowledge-based system that describe the relationship between input and the output variables are identified. Parameter identification method consist of two steps: 1-find fuzzy clusters to establish the number of fuzzy rules 2-optimize the rule consequents. This code perform a fuzzy clustering using subtractive clustering

Canny edge detector algorithm matlab codes This part gives the algorithm of Canny edge detector. The outputs are six subfigures shown in the same figure: • Subfigure 1: The initial "lena" • Subfigure 2: Edge detection along X-axis direction • Subfigure 3: Edge detection along Y-axis direction • Subfigure 4: The Norm of the image gradient • Subfigure 5: The Norm of the gradient after thresholding • Subfigure 6: The edges detected by thinning
