代码说明:

PCA的基本思想是将原来的指标重新组合成一组新的相互无关的几个综合指标来代替原来的指标。同时根据实际需要,从中可取几个较少的综合指标作为代表原来变量的总体性指标,尽可能多地反映原来的指标信息,达到降维的目的。        此程序在matlab环境下以PCA为基础进行了图像压缩和人脸识别两种算法的设计。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    需将图形文件复制到D盘根目录,或修改程序中的相关文件的路径。 计算机运行可能会出现这样的警告:Warning: Function call WAVEDEC2 invokes inexact match F:Matlab oolboxwaveletwaveletwavedec2.m. > In Wnn0802 at 18 无妨,没关系的,不影响运算结果。(Need to copy files to the D graphics root directory, or modify the program in the path of the relevant documents. Computer running such a warning might appear: Warning: Function call WAVEDEC2 invokes inexact match F: Matlab toolbox wavelet wavelet wavedec2.m> In Wnn0802 at 18 anyway, it does not matter, does not affect the result of the operation.)
