This is a property of orthogonal vectors of length 1.
这是长度为1的正交向量的性质。
This matrix can be simplified by using the properties of orthogonal vectors.
这个矩阵可以利用正交向量简化。
For any orthogonal vectors in the uncorrelated projection space, the obtained features in the original space are statistically uncorrelated.
对于无相关投影空间中的任何正交矢量集，其在原空间中的特征统计无关。
Compared with NPE algorithm, the orthogonal vectors have the better locality preserving power, thus the stronger discriminant power can be gotten and the error rate reduced.
利用邻域保护性能和特征的类别判别能力之间的关系，使得该算法提取的特征具有更好的分类性能。
