dct
在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中,发送者将载体图像分成8×8的像素块,每一块只精确地编码一个秘密信息位。嵌入过程开始时,首先伪随机地选择一个图像块bi,用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。
在通信开始前,发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致,让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频,确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失

Matlab-HW1
信号与系统matlab作业,实现卷积操作,供学习信号与系统的同学们参考(1. Define two signals as:
x1[n] =
n, 0 < n N1+1
2
N1 − n+ 1, N1+1
2 < n N1
0, elsewhere
and
x2[n] = 1, 0 < n N2
0, elsewhere
We let N1 = 999 and N2 = 500.
(a) (30 )Write a MATLAB function myconv to compute x1[n]x2[n] where
denotes the convolution sum. You have to plot your result and attach
it in your report. You may use the MATLAB function conv to check
whether your result is correct.)
