[Video Capture] USB摄像头视频读取实时处理

Description:

VFW效率比较高的USB摄像头视频读取＋实时处理，
FrameCallBack的效率高过拷贝到剪贴板再读取的操作

里面还有YUY2视频解码的处理，都替你弄好了！

overlay 显示模式替代 preview方式，大大减小CPU的负担。

效率虽然比不上DirectShow ，但是也可以了

将亮度曲线集成到 preview 窗口，放个手指在摄像头前面晃晃试一试。COOL 吧!!!

刚刚加入 slider ，尚未加入消息操作。

hujin@suda.edu.cn 如果觉得好，email给我一点好的源码！

[File Format] designforvideobasedonSDRAM

Description: 在信息处理中，特别是实时视频图像处理中，通常都要对实现视频图像进行处理，而这首先必须设计大容量的存储器，同步动态随机存储器SDRAM虽然有价格低廉、容量大等优点，但因SDRAM的控制结构复杂，常用的方法是设计SDRAM通用控制器，这使得很多人不得不放弃使用SDRAM而使用价格昂贵的SRAM。为此，笔者在研究有关文献的基础上，根据具体情况提出一种独特的方法，实现了对SDRAM的控制，并通过利用FPGA控制数据存取的顺序来实现对数字视频图像的旋转，截取、平移等实时处理。-In information processing, especially real-time video image processing usually have to deal with video images, which must first be designed large-capacity memory, synchronous dynamic random access memory SDRAM Although there are low cost, large capacity, etc., but SDRAM control structure of the complex, commonly used method is to design generic SDRAM controller, which makes a lot of people had to abandon the use of SDRAM and the use of expensive SRAM. To this end, the authors examine the literature based on the specific situation in a unique way to realize the control of SDRAM, and control data through the use of FPGA to realize the order of access to digital video image rotation, interception, translation, such as real-time processing.
