简介：等轴的设计(IsoProjection)是一个线性维数减小方法，它明确地考虑歧管在数据嵌入的结构。然而，IsoProjection是非直角的，它使它极其敏感到减少的空间的尺寸并且对估计困难内在的维数。non-orthogonality也弄歪在数据嵌入的公制的结构。这份报纸建议一个新方法叫了直角的等轴的设计(O-IsoProjection)，它分享象IsoProjection的一样的线性特性并且克服IsoProjection的公制的失真问题。类似于IsoProjection，O-IsoProjection第一构造能思考的一张毗邻图歧管在数据嵌入的结构和在样品之间的类关系脸空格指，然后由保存如此的图结构获得设计。与IsoProjection不同，O-IsoProjection要求直角的基础向量，和直角的基础向量能由反复的方法是计算的。ORL和耶鲁数据库上的试验性的结果证明O-IsoProjection让更好的识别比Eigenface，Fisherface和IsoProjection为脸识别评价。
