中文说明：毕业设计有用，信号维数的估计，粒子图像分割及匹配均为自行编制的子例程，借鉴了主成分分析算法（PCA），计算多重分形非趋势波动分析，是学习PCA特征提取的很好的学习资料。
English Description：
Graduation design useful, dimension of signal estimation, particle image segmentation and matching are self-made subroutine, using principal component analysis (PCA) algorithm, calculating the multifractal detrended fluctuation analysis, PCA learning feature extraction is to very good learning materials.
