Embedded-in-the-DCT-coefficients-
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。
(Information embedded in the DCT coefficients of the image, the image of the common 512* 512 size gray-scale (experimental image LENA.BMP). Information embedded in a binary Logo Figure (used in the experiment logo picture shows the tj-logo.bmp), the plot size 32* 32, 1024 Bit.
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.)

rgb to HSV,很有用,调试成功,可以应用(rgb to HSV,#include "stdafx.h"
#include <iostream.h>

医学图像配准,医学图像2D_3D配准,基于vc++开发。(The registration of pre-operative volumetric datasets to
intra-operative two-dimensional images provides an im-
provedway of verifying patient positionandmedical instru-
ment location. In applications from orthopedics to neuro-
surgery, it has a great value in maintaining up-to-date in-
formation about changes due to intervention. We propose a
mutual information-based registration algorithm which es-
tablishes the proper alignment via a stochastic gradient as-
centstrategy. Ourmaincontributionliesinestimatingprob-
ability density measures of image intensities with a sparse
histogrammingmethodwhichcouldlead to potentialspeed-
up over existing registration procedures and deriving the
gradient estimates required by the maximization procedure.
Experimental results are presented on fluoroscopy and CT
datasets of a real skull, and on a CT-derived dataset of a
real skull, a plastic skull and a plastic lumbar spine seg-
ment.)

MyGraphBrian
我改写后的graphbrian类,原本支持柱状图饼图和折线图的,现在添加了对这些图的风格调整,主要是增加了调整绘图区背景色和文本背景的功能,还增加了把图片保存为bmp文件的功能,以便用其他软件方便的打印。(I would then graphbrian category, which originally supported the pie chart histogram and line graph, and now added to adjust the style of these plans, the main adjustment is to increase the drawing area background color and text background function, but also an increase of the picture saved as bmp files, in order to use other software to facilitate printing.)
