Information-hiding
基于 DCT(离散余弦变换 )域的信息隐藏算法是目前应用最广的变换域算法 ,此类算法的最大不足是嵌信息量小。通过分析 DCT域隐藏算法隐藏容量少的原因 ,提出了一种大容量的 DCT域信息隐藏算法。算法首先对载体图像进行频谱均匀化处理 ,然后对图像进行全局 DCT变换 ,并将隐藏信息嵌入到载体图像的低频 DCT系数上 ,信息嵌入采用分段量化的方法实现 ,提取隐藏信息时不需要原始载体图像。实验结果表明 ,该算法的嵌入容量大 ,不可感知性好。(Based on DCT (discrete cosine transform) domain information hiding algorithm is the most widely used transform domain algorithms, the largest of these algorithms is the lack of a small amount of information embedded. Hiding Algorithm for DCT domain by analyzing the hidden reasons for the low capacity, a large capacity of information hiding algorithm for DCT domain. Firstly, the spectrum of the carrier image homogenization, and then the image is a global DCT transformation, and hidden information embedded into the image of the low-frequency DCT coefficients, the information embedded in the methods used to achieve sub-quantization, extract hidden information without the original Vector image. Experimental results show that the algorithm embedding capacity, can not be perceived good.)

a.阅读的图像img_1.tif，img_2.png的文件夹中，并
他们展示于一体，这两个数字分别。
（参考函数：imread, imshow, figure, subplot）
b.在matlab，观察从工作区中的图像信息面板
c.分别使用size, imfinfo,whos等功能获得的图像信息
d.添加标题的图像。 （参考函数：title）
Ë 。下面的代码实现的M文件编辑器
f=imread(‘img_1.tif’)
imshow(f)
set(figure(1), NumberTitle , off , Name , my first image’)
观察结果，并确定的功set()
f。保存img_1.tif目录“D： imagetest”。如果该文件夹不
存在，请首先创建这个新的文件夹。 （参考函数：imwrite）
(a. Read the images img_1.tif, img_2.png given in the folder, and
show them in one and two figures respectively.
(referenced function: imread, imshow, figure, subplot)
b. In matlab, observe the images information from the workspace
Panel
c. Use size, imfinfo,whos,etc functions to obtain image information
respectively.
d. Add title to the images. (referenced function: title)
e. Implement the following codes in the M-file Editor
f=imread(‘img_1.tif’)
imshow(f)
set(figure(1), NumberTitle , off , Name , my first image’)
observe the result, and determine the function of set()
f. Save img_1.tif to the directory “d:imagetest”. If the folder does not
exist, please create this new folder first. (referenced function:
imwrite))
