基于pca降维的特征不变特性变换方法（sift），希望对研究特征提取的朋友有帮助！...

本人收集的东西，不用Vb了，丢掉怪可惜的 分形算法与程序设计VB版 一书中所讲解的程序设计的源代码及部分供参考的效果图。-I collect things that do not have Vb, and unfortunately lost the strange fractal algorithm and program design VB version of one book on programming source code and some of the effects of plans for reference.
