程序功能是把一副倾斜的文字图像矫正过来，通过边缘检测再进行霍夫变换完成(The program function is to correct a skewed text image.)

说明：  根据一幅杂草和作物混合的图像可以识别出图像中的杂草(Weeds in the image can be identified according to a mixed image of weeds and crops)

这是我做的一个二维傅里叶变换的程序，可以对图像进行2DFFT变换得到频谱图，并利用2DIFFT得到原图像(I do a two-dimensional Fourier transform procedure, 2DFFT transform spectrogram image and utilize 2DIFFT original image)

这是新提出来的用于图像去噪的非局部均值滤波方法, matlab程序.非常好,你试试.(this is a new proposed image denoising method--non local means filtering, matlab file. you can try!)

水印攻击测试程序optimark。 这个比stirmark更全面测试水印程序，很好用(Watermark attack test program optimark. This more comprehensive test than stirmark watermark program, very good use)

图像数字水印中所涉及到的代码以及具体的文字的详细说明(The code involved in the image digital watermarking)

矩不变量，适用于图像匹配，数字水印，图像重建(Moment invariants, applicable to the image matching, digital watermarking, image reconstruction)

图像处理的峰值信噪比计算程序，简单精确，直接算出值(PSNR calculation program image processing, simple accurate, direct calculation value)

一个自由、开源的图形库--FreeImage3.92最新版的中文参考(支持位图构件―例如调色板和数据位―的便易访问；将位图从一种位深度转换到另一种位深度；当有多幅位图页―例如TIFF―时访问位图的不同页；基本的位图处理，如旋转、翻转（flipping）和重采样，或点操作，如亮度和对比度调整；Alpha混合与合成（Compositing and blending）；FreeImage不支持：高级图象处理操作，如回卷（Convolution）和变换（Transform）；位图绘制； 矢量图形。)(a free, revenue graphics library-- the latest version FreeImage3 .92 reference to the Chinese (support bitmap elements- such as transfer shade and data spaces- the easy access; will be from a bitmap-depth conversion to another kind of depth; When a number of bitmap page- such as TIFF- Bitmap to visit the different pages; basic bitmap processing, such as rotation, Upset (flipping) and resampling, or point operations, such as brightness and contrast adjustments; Alpha mixed with the synthetic (Compositing and blending); FreeImage not support : Advanced image processing operation, If the response (Convolution) and transform (Transform); bitmap rendering; Vector graphics.))

图像剪切后，转换为LAB和HSV颜色空间，计算每个颜色通道的颜色矩，最后将所有变量整合到一个矩阵中。(after image cropping, convert the image into LAB nd HSV color space, then computing the color moments of each channel. finally combine this variables into one matrix.)
