用系统调用signal()让父进程捕捉键盘上来的中断信号(按Ctrl-C键);当捕捉到中断信号后,父进程用系统调用kill()向两个子进程发出信号,子进程捕捉到信号后分别输出下列信息后终止: Child Process 1 is Killed by Parent! Child Process 2 is Killed by Parent! 父进程等待两个子进程终止后,输出如下的信息后终止: Parent Process is Killed!-with system call signal () so that the process of capturing the father onto the keyboard interrupt signal (Ctrl-C bond); When the interrupt signal capture, the father of the process of using system calls kill () to process two signals son, the child process to capture the signal output respectively after the termination of the following information : Process is a Child Killed by Parent! Process 2 Child is Killed by Parent! the process of waiting for the father of two-after the termination process, the following information output after termination : Parent Process is Killed!

demo目录:
fvs_enhancer:指纹增强程序,描述了如何使用该库增强指纹图像。原图像和目标图
像都是位图。
fvs_direction:描述了如何提取方向图。输入图像必须是归一化的图像,这样才能
有较好的效果。输出图像覆盖于输入图像之上。
fvs_createtestimages:该程序用来产生调试过程中可能会用到的一些位图图像,这
些图像是不同角度和不同间隔的条纹。产生图像的文件名命名方式如下:
testimgSSSDDD.bmp
其中,SSS代表条纹间隔(像素个数),DDD代表方向的角度。
fvs_thinner:描述了怎样细化一个指纹图像。细化后的图像尽可能的代表了指纹的
脊线。
fvs_minutia:显示了如何从细化后的指纹图像中获得细节点集合。这一部分目前做
的效果不好,提取出的伪细节点太多。
fvs_mask:计算有效的指纹区域(剔除非指纹区域以及模糊指纹区域)。
include目录:
包含了头文件。
src目录:
包含了指纹识别中各种算法的实现代码。这些代码的使用方法可以参见demo目录中的
例程。-demo directory : fvs_enhancer : fingerprint enhancement procedures describes how to enhance the use of the fingerprint image. The original image and objectives are bitmap images. Fvs_direction : describes how to extract the direction of the map. Input image must be a normalized image, in order to have better results. Image output coverage in the input image above. Fvs_createtestimages : The procedure used to produce debugging process may be used in some of Bitmap images, These i

我的URAL的1000 ~ 1050 的全部代码 包含WA 最后AC的程序 有2~3个比较难的是MAIGO的程序,另外源文件中附有题解,在linux下做的 如中文乱码请用word打开,应该对想做URAL的同学有一定帮助,另外请相信自己的能力 万不得以再看代码-My Ural 1000 ~ 1050 all the code that contains the procedures for WA Finally AC has 2 to 3 more difficult is the procedure MAIGO, another source file in question with a solution in linux to do next, such as the Chinese word garbled Please open, Ural should students want to have to some extent help Also, please believe that their abilities million may not look at the code
