画图工具

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。-fvs_enhancer : fingerprint enhancement procedures, a description of 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 images are different angles and different spacing of the fringes. Images produced a

实现8连通域标记，返回值为标记数，输入输出在源码中有相应的说明。标记效果经过上百次测试，没有问题。相应的动态库也添加，使用时用动态库即可。

用vc+mapobjects开发的源代码，实现鼠标多边形的移动-with vc MapObjects development of the source code, mouse polygon mobile

Function realized median filter with irregular mask by using Visual Studio, and OpenCV library. User can define mask by special matrix with unrestricted size N x M, which includes 0 and 1 values. Only 1 values determine which element of neighborhood of point will be used to calculate median.-Function realized median filter with irregular mask by using Visual Studio, and OpenCV library.

STM32 Cryptographic Library Introduction This manual describes the API of the STM32 cryptographic library (STM32-CRYP-LIB) that supports the following cryptographic algorithms:  AES-128, AES-192, AES-256 bits. Supported modes are: – ECB (Electronic Codebook Mode) – CBC (Cipher-Block Chaining) with support for ciphertext stealing – CTR (CounTer Mode) – CCM (Counter with CBC-MAC) – GCM (Galois Counter Mode) – CMAC – KEY WRAP  ARC4  DES, TripleDES. Supported modes are: – ECB (Electronic Codebook Mode) – CBC (Cipher-Block Chaining)  HASH functions with HMAC support: – MD5 – SHA-1 – SHA-224 – SHA-256  Random engine based on DRBG-AES-128  RSA signature functions with PKCS#1v1.5  ECC (Elliptic Curve Cryptography): – Key generation – Scalar multiplication (the base for ECDH) – ECDSA These cryptographic algorithms can run in the series STM32F1, STM32 L1, STM32F2, STM32F4, STM32F0 and STM32F3 with hardware enhancement accelerators.
