Description: 在许多领域的研究与应用中，往往需要对反映事物的多个变量进行大量的观测，收集大量数据以便进行分析寻找规律。多变量大样本无疑会为研究和应用提供了丰富的信息，但也在一定程度上增加了数据采集的工作量，更重要的是在多数情况下，许多变量之间可能存在相关性，从而增加了问题分析的复杂性，同时对分析带来不便。如果分别对每个指标进行分析，分析往往是孤立的，而不是综合的。盲目减少指标会损失很多信息，容易产生错误的结论。
因此需要找到一个合理的方法，在减少需要分析的指标同时，尽量减少原指标包含信息的损失，以达到对所收集数据进行全面分析的目的。由于各变量间存在一定的相关关系，因此有可能用较少的综合指标分别综合存在于各变量中的各类信息。主成分分析与因子分析就属于这类降维的方法。(* pca.cpp
This program demonstrates how to use OpenCV PCA with a specified amount of variance to retain. The effect is illustrated further by using a trackbar to change the value for retained varaince.
The program takes as input a text file with each line begin the full path to an image. PCA will be performed on this list of images. The author recommends using
the first 15 faces of the AT&T face data set:
