图像巴特沃斯陷波器，实现了简单的巴特沃斯陷波器滤除图像的某些频率的干扰(Image Butterworth notch filter, to achieve a simple Butterworth notch filter to filter out images of certain frequency interference)

说明：  标定用的c++程序，可以用来标定得到相机的内参矩阵和畸变参数。(Calibration using matlab toolbox, can be used to calibrate the camera s internal control matrix image obtained.)

实现了图片及目标图片的傅立叶变换，并得出了加载到空间光调制器上的相息图！(To achieve the target image and the image of the Fourier transform, and load to obtain a kinoform spatial light modulator on!)

DIC测试，适用于二维数字图像相关法，采用的ZNSSD，输入图像需为灰度图像，输出仿射矩阵(Measuring strain in samples which are too small, big, compliant, soft or hot are typical scenarios where non-contact techniques are needed. A technique which can cover all that and also can deal with complicated strain fields in structures or structural materials is the Digital Image Correlation. With this technique, strain can be calculated from a series of consecutive images with sub pixel resolution as will be shown in the following chapters.)

完整的图像加密算法以及对此算法加密结果的性能分析：像素之间相关性，图像的信息熵，以及NPCR,UACI(completely figure encryption scheme and corespond result analysis)

InSAR用于干涉的压缩包，有需要的可以下载啊(InSAR is used to interfere in the archive)

画板素描源码程序，根据画板底色与图像的颜色差异判断，对图像进行轮廓的素描。(Sketchpad sketch source program, according to the background and image color difference Sketchpad judgment sketch the outline of the image .)

使用Gabor小波对图像进行特征提取，代码可以直接使用(Using the Gabor wavelet feature extraction, the code can be used directly)

主要适用于图像分割，用的是马尔科夫随机场，非常好用(Mainly applicable to image segmentation, using the Markov random field, very easy to use)

实现凸多边形排样，使用临界多边形NFP判断两个凸多边形是否相交,使用启发式算法提高效率(It s a good implement of convex polygon stock.)
