重压缩检测：检测图像是否存在两次JPEG压缩并定位篡改区域(double JPEG detection)

一套完整的V-BLAST系统，包括发射端的多种调制以及多种接受算法，信道为瑞利信道。(A complete set of V-BLAST system, including a variety of modulation transmitter and a variety of acceptable algorithm, channel for the Rayleigh channel.)

1. 按照式计算相似性矩阵 2. 排除自身的相似度 3. 按照式计算归一化矩阵 4. 按照式计算归一化拉普拉斯图矩阵L 5. 计算L的特征向量，将前个特征值最大的向量按列放置成一个矩阵，即依次为前个特征值最大的特征向量 6. 归一化X形成矩阵Y 7. 对矩阵Y按每行为一个数据点，进行k-means聚类，第行所属的类就是原来所属的类。(1. similarity matrix based on formula computation 2. rule out your own similarity. 3. normalized matrix based on formula computation 4. normalized formula Laplasse matrix L according to formula. 5. Calculate the eigenvectors of L. Place the vectors with the largest eigenvalues in columns into a matrix, that is, the eigenvectors with the largest eigenvalues in turn. 6. normalized X formation matrix Y 7. K-means clustering is applied to matrix Y according to one data point per behavior. The first row belongs to the original class.)

德国人开发的地震处理分析软件，包括了塑性、弹性、加速度谱分析、频谱分析等。不过界面是德语的（看不懂，呵呵） (German development of seismic processing and analysis software, including plastic, elastic, the acceleration spectral analysis, spectrum analysis. But the interface is German (not read, Oh))

一种改进的快速独立分量分析方法，加入了匹配系数加以改进(An improved method of fast independent component analysis, be improved by adding a matching coefficient)

设计一个信号发生器,并同时画出信号的时域表 示，自相关函数及功率谱(Design of a signal generator and simultaneously draw the time domain representation of the signal, the autocorrelation function and the power spectrum)
