Description: 本程序实现二维灰度图像的小波变换和逆变换。
直接运行本目录下的批处理程序run即可。
用户需自己输入以下参数：
1. 图像文件名(lena.bmp，若使用其它图像请先放入本目录下)
2. 选用的小波名称(本程序中可使用haar及db2-db5)
3. 小波变换的级数。
运行结束后小波变换与逆变换结果分别保存在dec.bmp与rec.bmp中。-This procedure realize two-dimensional gray-scale image wavelet transform and inverse transform. Catalog under the direct operation of a batch process can run. Users need their own, enter the following parameters: 1. Image file name (lena.bmp, if the use of other images, please Add Catalog under) 2. Wavelet chosen name (This procedure can be used haar and db2-db5) 3. Wavelet Transform series. Run after the wavelet transform and inverse transform results are stored in dec.bmp in with rec.bmp.

Description: 在图像的DCT系数上嵌入信息，图像为常见的512*512大小的灰度图（实验所用图像为LENA.BMP）。嵌入的信息为一二进制Logo图（实验所用logo图为tj-logo.bmp），该图大小为32*32，共1024个Bit。
1. 在LENA图中嵌入水印，输出嵌入后的水印图像。
2. 对水印图像解码，输出解码后得到的logo图，并统计错误率。
3. 使用不同的嵌入强度进行嵌入，观察其对作品直觉效果和解码效果的影响，绘制相应的曲线。
4. 使用加入噪声、改变对比度、JPEG压缩等攻击方法对水印作品进行攻击，查看解码的效果。

LENA Figure embedded watermark, the watermark image output embedded.
(2) logo watermark image decoding, the output decoded Figure statistical error rate.
(3) using a different embedding strength for embedding, observe the works intuitive effects and decoding results, and draw the corresponding curve.
(4) by adding the noise, change the contrast, JPEG compression attack methods to attack, to see the effect of decoding the watermark works.

Description:
1.编写程序，完成灰度分段线性变换。如下图所示，输入两个点的坐标完成对图像的分段线性对比度拉伸。
2. 学习使用histeq函数，完成
①对’lena.bmp‘的直方图均衡化；
②以’cameraman.tif’的直方图为模板，将’lena.bmp’做直方图匹配。
3. 不使用histeq函数，自己编写程序完成直方图均衡化，并显示直方图均衡化前后的图像以及其直方图。
4. 不使用histeq函数，自己编写程序完成直方图匹配，显示匹配前后的图像、模板直方图和匹配过的直方图。
-1. Write a program to complete the gray piecewise linear transformation. As shown below, enter the coordinates of two points to complete the piecewise linear contrast of the image stretched. 2. Learn to use histeq function, complete ① on ' lena.bmp' histogram equalization ② to ' cameraman.tif' histogram as a template, the ' lena.bmp' do histogram matching. 3. Do not use histeq function, write your own program to complete histogram equalization, and display the image and its histogram before and after histogram equalization. 4. Do not use histeq function, write your own program to complete histogram matching, display images before and after the match, the template histogram and histogram matching too.
