一个图像拼接框架。切换注释与未注释代码可实现不同检测器与描述子的组合。默认使用SURF+BRIEF，通过预设重叠区域比例排除非重叠区域特征点的检测，提升特征点检测速度，减少误匹配。
An image stitching frame. The switching annotation and the non - annotated code can implement the combination of different detectors and descriptors. Using SURF+BRIEF by default, the detection of non overlapping region feature points is eliminated by setting default area ratio. The detection speed of feature points is improved and mismatch is reduced. (2018-01-14, C++, 2KB, 下载5次)

本文主要介绍下opencv中自带的一个随机数发生器的类RNG，这里我用这个类来画一些图形，和基础学习笔记之opencv(13)：基本绘图 一文中类似，只是 这里画出来图像的坐标，大小，颜色，角度等所有信息都是随机的，且是用RNG这个类产生的。参考文献为opencv自带tutiol及其代码。
开发环境：opencv2.4.2+Qt4.8.2+ubuntu12.04+QtCreator2.5
实验功能：
1. 该实验可以画6中几何图形和1个文本显示，每种都是画80个，每画完一个延时100ms。
2. 打开软件后，默认画的图为直线。可以在软件的左下角Drawing Type下拉列表中选择不同的几何绘画图形及文字，这6种几何图形分别为画直线，画矩形，画椭圆弧线，画多边形，画圆，画填充多边形。文本显示为显示“OpenCv Forever!”，选择完后在窗口中会自动显示其随机绘图过程，
3. 单击Close按钮，退出软件。

kalman滤波器收到好的结果基于c++和opencv
Tracking of rotating point.
Rotation speed is constant.
Both state and measurements vectors are 1D (a point angle),
Measurement is the real point angle+ gaussian noise.
The real and the estimated points are connected with yellow line segment,
the real and the measured points are connected with red line segment.
(if Kalman filter works correctly,
the yellow segment should be shorter than the red one).
Pressing any key (except ESC) will reset the tracking with a different speed.
Pressing ESC will stop the program. (2010-06-15, Visual C++, 6KB, 下载4次)
