基于PCA 和BP 神经网络的人脸识别方法是针对 PCA 方法中存在的高维数问题和它对未训 练过的样本识别率低的缺点而提出的。该方法在预处理的基础上，利用粗糙集对 PCA 降维处理后的人脸特征进行约简，提取其中分类能力强的特征，实现在识别精度不变的情况下，有效的去除冗余信息；然后将约简后的属性输入到神经网络进行规则提取，利用神经网络非线性映射和并行处理的特点，增强对人脸图像识别的泛化能力。实验证明，使用该方法在识别率上有一定的提高(Face recognition method based on PCA and BP Neural Network)

一维粒子滤波算法先建立状态模型和量测模型，再构造粒子滤波函数，通过统计分析得到估计后的状态变量，就是该算法的基本原理(One-dimensional particle filter algorithm to first establish a state model and measurement model, and then construct the particle filter function to be estimated by statistical analysis after the state variables, that is the basic principle of the algorithm )
