Spectrum-est

说明：  这是一个在matlab中实现灰度图像二值化的小程序(This is a gray image is implemented in the matlab binary applet)

Matlab 命令大全详细介绍了Matlab中常用函数的用法以及应用举例，包括数值计算函数、数学变换函数以及绘图函数等(The book of the usage of Matlab functions details the application of commonly used functions in Matlab and application examples, including the numerical functions, mathematical transformation functions and graphics functions and so on )

说明：  viterb算法是卷积码中重要的一种译码算法，程序中用MATLAB实现了VITERB的译码算法，并且写了信道编码程序和二进制码通过以p概率错误的信道程序(viterb algorithm is important as a convolutional code decoding algorithm, the program using MATLAB to achieve a VITERB the decoding algorithm, and wrote letters Road, binary coding process and the probability of error through a p-channel process)

暂时只支持jpeg2000支持的 cdf97 和spline53 可以这样来测试： x=imread( E:studyjpeg2000imageslena.tif ) ％ see the decomposition coefficients y=wavelift(x, 1, spl53 ) using spline 5/3 wavelet figure subplot(1,2,1) imshow(x) subplot(1,2,2) imshow(mat2gray(y)) ％ see the reconstruction precision yy=wavelift(x, 5) using cdf 9/7 wavelet ix=wavelift(yy,-5) inverse sum(sum((double(x)-ix).^2)) (only temporary support jpeg2000 support cdf97 and spline53 this can be measured Examination : x = imread (E : study jpeg2000 images lena.tif)% see the d ecomposition coefficients wavelift y = (x, 1, spl53) using spline 5/3 wavelet figure subplot (1,2,1) imshow (x) subplot (1,2, 2) imshow (mat2gray (y))% see the reconstructi on precision wavelift yy = (x, 5) using cdf 9/7 wavelet ix = wavelift (yy.-5) inverse sum (sum ((double (x)- ix). ^ 2)

这是一篇硕士论文,题目是多目标优化的遗传算法研究(This is a master' s thesis topic is a multi-objective optimization by genetic algorithm)

Nous avons effectué les tests en tenant compte des paramètres utilisés afin de mettre en évidence leur influence. Sur les deux images testées, nous avons constaté que l’espace colorimétrique utilisé pour calculer la différence colorimétrique entre deux régions (RVB ou L * a * b * ) ainsi que le mode de segmentation (progressive ou par priorité) influent sur les résultats de segmentation. Nous avons mis aussi en évidence l’importance du seuil, qui est décisif sur les résultats que l’en veut atteindre. Nous pouvons également con

参数假设检验：对差异进行定量的分析，确定其性质，是随机误差还是系统误差. 为给出两者界限，找一检验统计量T，在H0成立下其分布已知.(Parameter hypothesis test: a quantitative analysis of the differences, to determine its nature, is random error or system error. Is given two boundaries, looking for a test statistic T, its distribution under the establishment of the H0 known.)

说明：  MATLAB应用百例，里面是详细的源程序(MATLAB application of 100 cases, which are detailed source)

一个表情识别的源码。直接调用pca和svm函数。(an expression recognition of the source. Pca and direct calling svm function.)

abaqus中umat子程序，可计算混凝土塑性损伤(abaqus in umat subroutine calculate concrete plastic damage)
