this code is assemble rectifire matlab code

粒子群算法（PSO）优化BP神经网络，用来进行非线性的校正，效果良好(Particle swarm optimization (PSO) to optimize BP neural network, used for non-linear correction, to good effect)

Hilbert-Huang Transformmatlab程序，及word版程序详单，这种算法用于机械行业故障诊断(Hilbert-Huang Transformmatlab procedures, and single-word version of the procedure in detail, the algorithm for fault diagnosis of machinery industry)

利用Matlab编程实现对lena.bmp灰度图象进行QF=50和QF=40的压缩和解压缩，比较二者的PSNR，并且利用霍夫曼编码模拟信道中传输图象。通过了Matlab2009A测试。(Using Matlab program to compress and decompress the gray image Lena.bmp at QF = 50 and QF = 40,as well as comparing the result of two situation.Then using Huffman coding analog channels transmitted images. Adopted Matlab2009A test.)

结合DCT和NNC进行人脸识别。先利用DCT提取特征，然后利用最近邻分类器分类，在ORL人脸库上测试效果不错。(The combination of DCT and NNC for face recognition. First DCT Feature Extraction, and then use the nearest neighbor classifiers, good test results on the ORL face database.)
