matlab实现LSB算法
用Matlab实现LSB算法,包括信息隐藏和提取。
LSB(LeastSignificant Bits)算法:将秘密信息嵌入到载体图像像素值的最低有效位,也称最不显著位,改变这一位置对载体图像的品质影响最小。
LSB算法的基本原理:
对空域的LSB做替换,用来替换LSB的序列就是需要加入的水印信息、水印的数字摘要或者由水印生成的伪随机序列。由于水印信息嵌入的位置是LSB,为了满足水印的不可见性,允许嵌入的水印强度不可能太高。然而针对空域的各种处理,如游程编码前的预处理,会对不显著分量进行一定的压缩,所以LSB算法对这些操作很敏感。因此LSB算法最初是用于脆弱性水印的。

BABP
由于BP神经网络易陷入局部最优,我们利用蝙蝠算法来优化BP的参数,以此找到最优的参数,并作为BP参数的初始值,用来做预测,效果很好!(Due to the BP neural network into local optimum easily, we use the bat algorithm to optimize the parameters of BP, to find the optimal parameters, and as the initial value of parameters of BP is used to do prediction, the effect is very good!)
