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

The Valgrind distribution has multiple tools. The most popular is the memory checking tool (called Memcheck) which can detect many common memory errors such as: * touching memory you shouldn t (eg. overrunning heap block boundaries) * using values before they have been initialized * incorrect freeing of memory, such as double-freeing heap blocks * memory leaks. -The Valgrind distribution has to multiple ols.
