这是一篇介绍图像分类的英文文章，是很好的资源(This is an introductory article in English image classification is a good resource)

pfx格式或者p121格式文件的解析器， PfxTest文件 使用一个BASE64编码的P12文件字节数组，默认密码123456，CERT为三级证书，使用BC库作为JCE实现(pfx test java code , decrypt a p12 format file (such as .pfx,.p12 file) the pfxtest use a sampled p12 file which is base64 encoded, the pfx password is 123456, and is an three level cert chain, the resolve use the BC lib ——the JCE open implemention)

三维重构技术，里面有详细的介绍。其开发环境matlab(Three-dimensional reconstruction technique, which has a detailed introduction. Their development environment matlab)

神经网络进行语音识别：/enframe.m，该函数将输入向量分为固定长度固定重叠量的帧。/SampleCreate.m,将取所有音频的mfcc系数处理成神经网络函数所需的输入格式(Neural networks for speech recognition)

FloatArrayBuffer, ReadWriteFloatArrayBuffer and ReadOnlyFloatArrayBuffer compose the implementation of array based float buffers.

摘　要:根据HFC网络上行信道的特性,建立了信道模型 分析了上行信道中存在的各种噪声对QPSK 调制技术的影响。结果表明在C /N (传输信道载噪比)较低的情况下,采用QPSK调制方式,可以提高系 统的抗干扰能力。 关键词: QPSK 光纤同轴电缆混合网 上行信道 噪声(Abstract: HFC network in accordance with the characteristics of the uplink channel, the establishment of a channel model an analysis of the various uplink channel noise on the impact of QPSK modulation. The results show that the C/N (transmission channel carrier-to-noise ratio) lower, the use of QPSK modulation, can improve the system of anti-interference ability. Keywords: QPSK hybrid fiber coaxial cable network uplink channel noise)

一本MATLAB在光学工程方面应用的好书(A MATLAB application in optical engineering books)

This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is pixel by pixel. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.

这三个小程序都是matlab的.m文件，分别实现用灰度变换的方法增强图像的对比度和直方图均匀化，模拟图像受高斯白噪声和椒盐噪声的影响。(The three procedures are Matlab. M documents, were used to achieve gray transform method to enhance the contrast of the image and histogram equalization. Simulation images by white Gaussian noise and the noise of Salt and Pepper.)
