基于人脸图像的年龄预测
人脸年龄检测的matlab例子。在人脸图像的基础上,利用pca,svm等机器学习的方法预测出人脸的大致年龄段。年龄段分为0-19岁,20-39岁,40-59岁,60岁以上。实验数据是FG-NET Aging Database。本例子在Image文件夹中存有77人不同改年龄的人脸原始图像,共935张;在Points文件夹中是这些人脸原始图像对应的用于表示人脸特征的形状特征标定点,每张68个标定点。例子很完整,注释详细。

基于遗传算法的BP神经网络MATLAB代码
由于BP网络的权值优化是一个无约束优化问题,而且权值要采用实数编码,所以直接利用Matlab遗传算法工具箱。贴出的代码是为一个19输入变量,1个输出变量情况下的非线性回归而设计的,如果要应用于其它情况,只需改动编解码函数即可。
