BP-classification BP神经网络图像分类程序

BP神经网络图像分类程序,代码很好懂，适合初学者。样本选的不是很大。

%<----------------------------!运用BP网络进行图像分类--------------------------->
%读入样本10即遥感图像的背景
I=imread（‘10.jpg‘）;
%将样本图像降维处理
R=I（::1）;
G=I（::2）;
B=I（::3）;
%灰度值归一化
R=im2double（R）;
G=im2double（G）;
B=im2double（B）;
[M N]=size（R）;
R=reshape（R‘[1 M*N]）;
G=reshape（G‘[1 M*N]）;
B=reshape（B‘[1 M*N]）;
%初始化输入矢量P和输出矢量T
P=[];
T=[];
P=[R;G;B];
T=[0;0;0];
[m n]=size（P）;
T=concur（Tn）;

%读入样本图像0
I=imread（‘0.jpg‘）;
%将样本图像降维处理
R=I（::1）;
G=I（::2）;
B=I（::3）;
%灰度值归一化
R=im2double（R）;
G=im2double（G）;
B=im2double（B）;
[M N]=size（R）;
R=reshape（R‘[1 M*N]）;
G=reshape（G‘[1 M*N]）;
B=reshape（B‘[1 M*N]）;
P1=[R;G;B];
T1=[0.1;0.3;0.5];
P=[PP1];
[m n]=size（P1）;
T1=concur（T1n）;
T=[TT1];

%读入样本图像1
I=imread（‘1.jpg‘）;
%将样本图像降维处理
R=I（::1）;
G=I（::2）;
