Description: 在MATLAB上所使用的PCA程序，主要應用於過濾相對較不重要的特徵值(dimension)，例如在三度空間的某些點具有(x,y,z)值，因為這些點有共同的一個持徵，就是z值相對於x,y值來得小很多(不明顯)，所以就以X,Y軸來表示這些點。此時就達成去除掉z的特徵值(dimension)。
-MATLAB used in the PCA procedure, mainly used in filtering relatively unimportant eigenvalue (dimension), for example, in some points with three-dimensional (x, y, z) values, because these points have a common one sign holders, that is, z values compared with the x, y values much smaller than (not obvious), so on to X, Y axis to express these points. Reached at this time to get rid of z eigenvalues (dimension).

Description: 针对四元数矩阵正交特征矢量系求解困难的缺点, 本文提出一种获取四元数矩阵正交特征矢量集等效、便捷的方法,
其基本思路为: 首先, 构造四元数矩阵定义于复数域的导出阵, 并利用该导出阵特征矢量空间的一种特殊的等价空间间接获取
相应特征值所对应的特征矢量. 然后, 将复数矢量转换为四元数矢量, 按如此方式获取的对应所有特征值的非零特征矢量则构
成原始四元数矩阵的正交特征矢量系-For Quaternion orthogonal feature vector lines to solve the shortcomings of the difficulties, this paper proposes a quaternion matrix to obtain the orthogonal feature vector set equivalent, and convenient method, and its basic idea is: First of all, the structure definition of quaternion matrix in the complex field of the export array, and use the Export feature vector array space equivalent of a special space for indirect access to the corresponding eigenvalues of the corresponding feature vector. Then, the plural vector is converted to quaternion vector, according to such methods to obtain all the characteristics of the corresponding non-zero value of feature vector constituted the original quaternion matrix of the orthogonal feature vector lines

Description: （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象；
（2）将所有子图象按列相接变成一个81维的行向量；
（3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量；
（4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。
