1.设计一个程序，对一幅灰度图像的实现如下几何变换,1)放大为原图1.5倍 2)绕中心旋转30度(CW) 3)采用偏移量插值实现一个透视变换. 灰度差值用最近邻插值和双线性插值 2. 绘制一幅灰度图像的梯度幅度图像（三点法求梯度），针对梯度幅度图像合理的选择一个阈值（通过试验即可）将其二值化，以获得图像边缘检测图像。 ((1) design a program, a grayscale image as geometric transformation, zoom 1) for 1.5 times the original 2) around the center of rotation of 30 degrees (CW) 3) interpolation of the offset to achieve a perspective transformation.gray level difference between the nearest neighbor interpolation and bilinear interpolation (2) draw a grayscale image of the gradient magnitude image (three-point method seeking gradient), the gradient magnitude image is reasonable to select a threshold value (the test can be) the second value to the image edge detection image.)

把jpg或bmp图片转换为AVI视频的C#版程序，但功能相对简单，需要大家继续丰富。(Jpg or bmp image to convert the C# version of AVI video program, but the function is relatively simple, we should all continue to enrich.)

卡尔曼滤波、无迹卡尔曼滤波、扩展卡尔曼滤波等滤波程序，本人收集了实验室所有这个方面的程序，欢迎大家下载，非常好用~(Kalman filtering, unscented Kalman filter, extended Kalman filtering, filtering program, I collected all the aspects of laboratory procedures, are welcome to download and very easy to use ~)

说明：  在图像处理中如何进行视频处理，如何从yuv格式的序列中提取出亮度信息，这是后面对视频处理的基础。(In image processing for video How to deal with how to format yuv sequence information extracted brightness, this is the basis of the face of video processing.)

在进行图像显著性分析时，要通过PR曲线进行比较不同方法的好坏，这个源码可以实现此功能。(Significantly during image analysis, through PR curves comparing different methods is good or bad, this source can achieve this functionality.)

说明：  Matlab编写的程序代码，包括基于肤色的人脸检测，根据人脸图像判别眼睛的状态（睁眼及闭眼）(Matlab program written in code, including color-based face detection, face image in accordance with the state of discriminant eyes (eyes open and eyes closed))

讲解滤波与二值图像处理，比较简单的图像处理源码(Explain the filtering and binary image processing, image processing source code is relatively simple)

一个维纳滤波器图像恢复的MATLAB原码(A Wiener filter image restoration of the original MATLAB code)

校正图像倾斜的程序，很好用，可以纠正几何投影变形(Image tilt correction procedures, very good use, you can correct the distortion geometric projection)
