BP-and-OMP

用来实现二维离散傅里叶变换的简单实用程序，在matlab中能快速得到理想结果(To realise 2-D Discrete wavelets transform，easily and effective to reach the ideal result we want！)

本人修改过的elm的matlab算法，该算法比原来的elm的算法在超过3个神经元后的计算速度能明显加快！原理是运用函数产生列矩阵！！ ELM 是一种快速的神经网络算法，本人已经比较过，比很多流行的算法（BP,SVM）都快,而且效果很好，运行环境是matlab，可以测试所有的benchmark的数据(I modified elm of matlab algorithm elm than the original algorithm in more than three neurons after the computing speed can significantly speed up! The principle is to use functions to generate the matrix out! ! ELM is a fast neural network algorithm, I have a comparison, than many popular algorithms (BP, SVM) faster, and the effect of good operating environment is matlab, you can test all of the benchmark data)

matlab code for LOLIMOT algorithm

Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.

LDA算法的matlab程序。本代码是对一维信号进行LDA降维处理的函数。(LDA algorithm matlab program. This code is a one-dimensional signal processing functions LDA dimensionality reduction.)

Resistivity of various types of materials

基于多相结构的信道化接收机，包含特征值与特征向量的提取、训练样本以及最后的识别，自写曲率计算函数 。( Channelized receiver based on multi-phase structure, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Since writing the curvature calculation function.)

关于信息恢复的程序。输入恢复类型、恢复向量导引和测度矩阵即可恢复出原向量。测度矩阵可以通过getmat.m文件生成。(With regard to the information recovery procedures. Enter recovery type, to restore vector guide and measure matrix can be restored to the original vector. The measurement matrix through getmat.m file generation.)
