Description: EasyBMPtoAVI is a simple, easy-to-use, cross-platform
utility for creating an avi movie file from a series
of windows bitmap (BMP) images. Some features:
1) Support for reading all bit-depths supported by
EasyBMP. At the present time, this includes 1,
4, 8, 16, 24, and 32-bpp bitmap images.
2) Can create files up to 2GB in size.
3) Output is uncompressed, so you can choose your own
compression without loss of quality.
4) Cross-platform compatible (Linux, Unix, Windows,
Macintosh, Solaris, ...)
5) Cross-compiler compatible (supports compiling in
MS Visual Studio, g++, MinGW, Intel s icc,
and the lousy Borland compiler)
6) Easy user interface even helps you if you forget
to specify crucial information.
7) Endian-safe as of Version 0.52, so it will work
on things like PowerPC, Sparc, etc.
8) 64-bit compatible if you compile with EasyBMP

Description: LinCAN is a Linux kernel module that implements a CAN driver capable of working with multiple cards, even with different chips and IO methods. Each communication object can be accessed from multiple applications concurrently.
It supports RT-Linux, 2.2, 2.4, and 2.6 with fully implemented select, poll, fasync, O_NONBLOCK, and O_SYNC semantics and multithreaded read/write capabilities. It works with the common Intel i82527, Philips 82c200, and Philips SJA1000 (in standard and PeliCAN mode) CAN controllers.
LinCAN project is part of a set of CAN/CANopen related components developed as part of OCERA framework.

Description: Linux 2.4.18 s3c2440 led driver
使用dev-C++撰寫，需要linux 2.4.18 kernel include，編譯完成後產生led module。
insmod main.o //安裝模組
mknod /dev/leds c 221 0
使用方法：
int main(int argc, char *argv[])
{
int testdev
//led test...
testdev = open("/dev/QuickMarkLed",O_RDWR)
ioctl(testdev, 2, 1) //ioctl(device, led number, open/close) open=1
ioctl(testdev, argv[1][0]- 0 , argv[2][0]- 0 ) //ioctl(device, led number, open/close) open=1
close(testdev)
return 0
}
-Linux 2.4.18 s3c2440 led driver to use dev-C++ Writing, the need for linux 2.4.18 kernel include, compiled after the completion of led module. insmod main.o// install the module mknod/dev/leds c 221 0 to use: int main (int argc, char* argv []) (int testdev// led test ... testdev = open (/ dev/QuickMarkLed , O_RDWR) ioctl (testdev, 2, 1)// ioctl (device, led number, open/close) open = 1 ioctl (testdev, argv [1] [0]- 0, argv [2] [0]- 0 )// ioctl (device, led number, open/close) open = 1 close (testdev) return 0)

Description: 数据类型"socklen_t"和int应该具有相同的长度.否则就会破坏 BSD套接字层的填充.POSIX开始的时候用的是size_t, Linus Torvalds(他希望有更多的人,但显然不是很多) 努力向他们解释使用size_t是完全错误的,因为在64位结构中 size_t和int的长度是不一样的,而这个参数(也就是accept函数的第三参数)的长度必须和int一致,因为这是BSD套接字接口标准.最终POSIX的那帮家伙找到了解决的办法,那就是创造了一个新的类型"socklen_t".Linux Torvalds说这是由于他们发现了自己的错误但又不好意思向大家伙儿承认,所以另外创造了一个新的数据类型.-Data type

Description: 用多线程同步方法解决读者阅览问题
1) 每个读者进入阅览室后，即时显示“Entered” 及其线程自定义标识，还同时显示阅览室共有几名顾客及其所坐的位置。
2) 至少有10个读者，每人阅览至少3秒钟。
3) 多个读者须共享操作函数代码。
2总的设计思想及系统平台、语言、工具：
设计思想：程序设定的是10个读者和5个座位，对读者进行编号，依次进入阅览室读书，为每一座位列一表目,包括座号和读者号等,读者离开时要登出，即消掉登记的信息。
系统平台：LINUX 语言：C语言 工具：vi编辑器、gcc编译器
操作系统:linux操作系统
调试工具：edit、masm、link、debug.
3数据结构与模块说明（功能与流程图）
数据结构
int count=0 //记录阅览室读者数量
sem_t full //定义阅览室座位信号量
int seat[5] //用数组表示座位
pthread_t reader[10] //定义读者线程
pthread_mutex_t mutex //定义互斥量
3.2功能说明
可以标识读者，随机为读者设置在阅览室的读书时间
可以显示阅览室读者的人数
可以显示读者所坐的位置，座位状态以及列出空座位

Description: 为了快速精确地对一个实体进行的三维重建, 提出了一种新的混合建模方法. 该方法利用同一实体在不同视
点下的多幅深度图像, 根据它们之间颜色和纹理的相关性, 通过逆投影变换, 可将图像中象素点映射到三维空间中的正
确位置. 然后再经模型重建和重投影, 可获取实体在任意视点下的图像. 实验结果表明, 这种建模方法具有复杂度恒定、
获取图像真实感强等优点, 适用于形状、 结构复杂的物体的重建.-: In o rder to reconst ruct th ree di mensi on model of an object, a new method of hybr id modeling is p resented .
