C#二维CAD制图软件，可以画简单的图形，并支持文件读取和保存(C#-D CAD drawing software, you can draw simple graphics, and supporting documents to read and save the)

MATLAB编写的角点检测程序，用于对目标的检测和稳定的跟踪。很适合对于运动目标的跟踪。(Corner detection procedures written in MATLAB for target detection and tracking. Very suitable for tracking of moving targets.)

傅里叶轮廓变换术，通过单幅条纹图像提取相位，最后根据上述信息，模拟曲面轮廓(Contour Fourier transform technique, through single stripe image extraction phase, the last light of the above information, an analog surface profile)

用vc编写的一个多边形变换程序(vc prepared using a polygon transformation process)

说明：  基于图像序列的单目三维重建，运用运动恢复结构，SIFT算法等(Monocular 3D reconstruction based on image sequence, using motion recovery structure, SIFT algorithm, etc.)

说明：  x射线的CT图像重建，内附data.mat为实际X射线拍到投影图像。(x-ray CT image reconstruction, the actual X-ray included data.mat photographed the projected image.)

说明：  通过设置5个不同的时域窗尺度和8个方向（theta），得到40个Gabor滤波器。但在滤波器显示的时候出现了问题。以下分别把程序的源代码、调用代码(Forty Gabor filters are obtained by setting 5 different time window scales and 8 directions (theta). But there was a problem when the filter was displayed. The following procedures are the source code, call code)

最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller.)

可以实现图像篡改检测，附带有几张图片，检测效果一般(Image tamper detection can be achieved, with pictures, the detection effect is general)

简单的GUI,可以作为学习,也可以自己根据基类作扩展(Simple GUI can be used as learning can also be the base class for the extension)
