% 文件名:randlsbget.m
% 程序员:余波
% 编写时间:2007.6.25
% 函数功能: 本函数将完成提取隐秘于上的秘密信息
% 输入格式举例:result=( scover.jpg ,56, secret.txt ,2001)
% 参数说明:
% output是信息隐藏后的图象
% len_total是秘密信息的长度
% goalfile是提取出的秘密信息文件
% key是随机间隔函数的密钥
% result是提取的信息
function result=randlsbget(output,len_total,goalfile,key)
ste_cover=imread(output)
ste_cover=double(ste_cover)
% 判断嵌入信息量是否过大
[m,n]=size(ste_cover)
frr=fopen(goalfile, a )
% p作为信息嵌入位计数器将信息序列写回文本文件
p=1
% 调用随机间隔函数选取像素点
[row,col]=randinterval(ste_cover,len_toal,key)
for i=:len_toal
if bitand(ste_cover(row(i),col(i)),1)==1
fwrite(frr,1, bit1 )
result(p,1)
else
fwrite(frr,0, bit1 )
result(p,1)=0
end
if p==len_total
break
end
p=p+1
end
fclose(frr)

LDSandNLDS
本人在硕士毕业论文时使用的和修改的代码,主要是用于使用LDS和NLDS模型对火焰视频进行建模,并可以模拟出来火焰来,同时使用LDS和NLDS模型参数对不同类型视频进行分类(我们主要是对识别火焰),里面有实验结果。(I used in the Master s Thesis and modify the code, mainly for LDS and NLDS model modeling the flame video, and can be simulated flame using both LDS and NLDS model parameters to classify the different types of video (we mainly on identification flame), there are experimental results.)
