使用说明 使用时打开此例题目录下pic中的图片，然后依次单击按钮“转”、“1”、“2”、“3”、“4”和“5”，就可以实现精确的车牌定位。 具体步骤 1.24位真彩色->256色灰度图。 2.预处理:中值滤波。 3.二值化:用一个初始阈值T对图像A进行二值化得到二值化图像B。 初始阈值T的确定方法是:选择阈值T=Gmax-(Gmax-Gmin)/3,Gmax和Gmin分别是最高、最低灰度值。 该阈值对不同牌照有一定的适应性,能够保证背景基本被置为0,以突出牌照区域。 4.削弱背景干扰。对图像B做简单的相邻像素灰度值相减,得到新的图像G,即Gi,j=|Pi,j-Pi,j-1|i=0,1,…,439 j=0,1,…,639Gi,0=Pi,0,左边缘直接赋值,不会影响整体效果。 5.用自定义模板进行中值滤波 区域灰度基本被赋值为0。考虑到文字是由许多短竖线组成,而背景噪声有一大部分是孤立噪声,用模板(1,1,1,1,1)T对G进行中值滤波,能够得到除掉了大部分干扰的图像C。 6.牌照搜索:利用水平投影法检测车牌水平位置,利用垂直投影法检测车牌垂直位置。 7.区域裁剪,截取车牌图像。-my english is poor

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.
