摄像机标定程序，实现单目，双目摄像机的标定(calibration of camera )

汽车识别，计数源代码 通过opencv色差提取，对移动的车辆进行识别 当已经识别的车辆通过定义直线时候，进行计数(Vehicle identification, counting opencv source code by extracting the color of a moving vehicle to identify when a vehicle has been identified by defining a straight line when counting)

主要包括3种去噪方法，Bayesian Least Squares，BM3d 和Non-local means (this attachment contains three classical denoising methods Bayesian Least Squares，BM3d and Non-local means )

对一维信号，用正交重叠变换做DCT和逆DCT(Of one-dimensional signals, using orthogonal lapped transform DCT and inverse DCT to do)

本算法可实现图形裁剪，并将0°，45°，90°，135°四角度偏振图像合成强度图像，偏振度图像，偏振角图像，椭圆偏振率图像(This algorithm can realize graphic cutting and synthesize intensity images of 0, 45, 90, 135, four angles, polarization image, polarization angle image, elliptical polarization image)

此matlab程序用于横向和纵向都被剪碎的纸片的拼接复原，高质量(This matlab program is used for the stitching of both horizontal and vertical pieces that are cut and broken, and of high quality)

说明：  机载正侧视SAR雷达仿真和成像，使用matlab编写，直接运行可用(Simulation and imaging of airborne forward-looking SAR radar)

有关投影的光学资料,针对DLP的几何光学(Information on the projection optics, geometrical optics for DLP)

60轨CAD断面图，严格按照国家标准作图，60轨CAD断面图(Cross-sectional drawing of 60-rail CAD)

说明：  dct域的图像数字水印，将水印图像信息隐藏在DCT系数的中频部分。(DCT domain image watermarking, the watermark image information hidden in the intermediate frequency part of DCT coefficients.)
