After extending the definition of tangent distance,we extract the directions of variance of sample sets using Singular Value Decomposition based onthe original image, and use them as the tangent vectors of training sample sets.

本文把切线距离的概念进行了进一步的延伸，在原始图像的基础上，用奇异值分解方法直接提取样本集合中所包含变化的方向，作为训练样本的切线向量。

R2 The adjusted R2 is 1 minus the ratio of sample variance of the OLS residuals (after correcting the degrees of freedom) to the sample variance of y.

Another advantage of these improved methods is the flexibility of rendering multiple volume data sets. There is detailed analysis and experimental proof of this flexibility. Besides, since the sample variance can reflect sample value distribution, an enhancement algorithm based on variance statistic is proposed.

另外，本文根据样本距统计量能够反映样本数据值分布的特点，提出基于方差统计的增强算法，绘制结果能够突出显示局部方差统计值较大，即结构分布较复杂的区域。
