Directional Weighted median filter for random value impulse noise removal

本段代码主要是为了实现讲多光谱图像进行光谱分离然后再合并成一种可以在matlab中显示的格式.tif的图像，同时保证了原始的图像信息不丢失(This code is mainly to achieve multispectral images speak for spectral separation and then combined into a format that can be displayed in matlab. Tif image, while maintaining the original image information is not lost)

非平衡数据集的分类问题经常出现在许多实际应用中.支持向量机在处理这一类问题时,整体分类性能比较低.为此,Veropoulos提出的采用不同惩罚系数的改进算法可以较好的解决此类问题.此外,可以利用序列最小优化算法简单快速的解决上述优化问题.(Non-equilibrium data sets classification problems often appear in many practical applications. Support Vector Machine in dealing with this type of issue, the overall classification performance is relatively low. To this end, Veropoulos proposed punishment coefficient using different algorithms can improve the better solution such issues. In addition, can use the Sequential Minimal Optimization algorithm is simple and fast solution to the above optimization problem.)

实现瑞利信道下M阶QAM调制的EGC接收仿真，并与MRC理论上的SER和BER性能对照(Implementation under Rayleigh channel EGC receive simulation, M order QAM modulation and with MRC theory SER and BER performance comparison.)

说明：  EMD的扩展算法，集合经验模态分解(EEMD)， 程序完整可运行(Extension algorithm of EMD, ensemble empirical mode decomposition (EEMD), complete and runnable program)

用割平面法求解整数规划。先不考虑整数约束条件，求松弛问题的最优解，如果获得整数最优解，即为所求，运算停止．如果所得到最优解不满足整数约束条件，则在此非整数解的基础上增加新的约束条件重新求解．(By cutting plane method for solving integer programming. Not considered integer constraints, the optimal solution relaxation problem, if the integer obtained optimal solution is sought, and operation stops. If the optimal solution does not satisfy the integer constraints, then on the basis of this non-integer solutions adding new constraints on the re-solving.)
