用于粒子图像测速技术的图像处理，分析得到流场信息(Image Processing for Particle Image Velocimetry and Flow Field Information Analysis)

matlab 高动态图像 读取的hdr格式的读取文件，经测试可以用(matlab read hdr high dynamic image to read the file format, the test can be used)

本文实现了Retinex算法，支持对图像的去雾灯操作，是一种图像增强的方法。(this paper present a new image strength method-Retinex impliment by opencv)

说明：  思想：把原始图的直方图变换为均匀分布的形式，这样就增加了灰度值的动态 范围从而达到增强图像整体对比度的效果。其优点是能自动地增强整个 图像的对比度。 1、对灰度图像进行直方图的均衡化处理，达到图像增强的目的。 2、利用平均滤波和中值滤波对图像进行平滑滤波。 3、利用拉普拉斯运算对图像进行锐化滤波。(Idea: transform the histogram of the original image into the form of uniform distribution, so as to increase the dynamic gray value Range to enhance the overall contrast of the image. Its advantage is that it can automatically enhance the contrast of the whole image. 1. The gray image is processed by histogram equalization to achieve the purpose of image enhancement. 2. Average filter and median filter are used to smooth the image. 3. Using Laplace operation to sharpen the image.)

此demo演示的是一个能够检测并跟踪道路上的标记线并且在适当时机发出报警的系统，此系统可使汽车在行驶过程中能够避免偏离车道。系统由一台摄像机，一台计算机，以及一个扬声器组成，摄像机采集视频信息交由计算机处理，根据处理结果控制扬声器是否报警。(This demo demonstrates a system that detects and tracks the marking lines on the road and sends out the alarm at the right time, which enables the car to avoid deviating from the driveway during the driving process. The system is composed of a camera, a computer, and a loudspeaker. The video information is processed by the camera to control the alarm of the speaker according to the processing results.)

CBIR系统中采用的tamura纹理特征计算程序(Tamura texture features used in CBIR system calculation program)

此程序是我进行视频处理时入门的程序，包含视频检测和轮廓跟踪，希望对大家有用(This program is my entry for video processing procedures, including video detection and contour tracing, hope for all of us)

简化数据模型、减少数据处理时间、提高成型效率。算法无需建立三角面片之间的拓扑关系，可直接进行切片分层，切平面与网格面片所得的交线段也无需排序，节省了生成轮廓线时对交线段重新排序所需的时间，提高了分层处理的效率。(Simplify the data model, and to reduce the data processing time and improve the molding efficiency. Algorithm without establishing the topological relationships between the triangular dough piece, can be directly slice layered tangential plane with the grid cross-segment of the dough piece obtained without sorting, save when the contour line is generated on the cross segment reordering the time required, improve the efficiency of the hierarchical processing.)
