：数字水印技术作为数字媒体版权保护的有效办法，近年来在国内外引起了人们极大的兴趣。作者采用了DCT离散余弦变换的算法，对图像这种多媒体数字作品进行了数字水印的嵌入和检测研究。并且使用了高效实用的编程工具MATLAB来介绍了一种DCT域的图像数字水印嵌入和提取的(BASIC_WM.M ..........................................cellauto.m ..........................................dctwatermark.m ..........................................detectbasic_wm.m ..........................................plotcorr_coef.m ..........................................wavedetect.m ..........................................wavedetect2.m ..........................................wavemarksvd.m ..........................................wavemarksvd)

单尺度SSR(Single Scale Retinex)(A Retinex Function)

使用hough变换检测图像中的线条；包括main函数和其他4个操作函数，有实验图片！(Detection using hough transform image lines including the main function and operation of the other four functions, there are experimental picture!)

在VS2012平台上利用C++语言和opencv实现对图像的分块，并保存分块图像(Using the C++ language and OpenCV to block the image on the VS2012 platform and save the block image)

用其中一半的数据采用ANN-BP算法设计分类器，另一半数据用于测试分类器性能。(Half of them with the data ANN-BP algorithm design classifier, and the other half data used to test the performance of classification. )

IMU姿态跟踪，利用粒子滤波器实现，可用于机器人姿态确定(IMU orientation tracking algorithm using particle filter.)

说明：  火灾预警系统，实现火焰的特征提取，结合SVM分类算法(Fire early warning system, to achieve the feature extraction of flame, combined with SVM classification algorithm)

使用radon变换来实现对图像中直线的检测，显示检测结果(Use radon detection of image transformation to achieve straight line, showing the test results)

说明：  非常好用的基于各种常用滤波器的图像平滑算法(Translate From: Chinese To: English EnglishChineseArabicTranslate text or webpage 非常好用的基于各种常用滤波器的图像平滑算法 Translate from: Japanese Allow phonetic typingType text or a website address or translate a document.

matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如未修改，可提取隐藏信息。当有修改发生时，可以定位修改的位置，并在图上标出。标识面积占修改面积的75％，一般修改都能标出(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications)
