针对夜间动态背景下的行人检测中分割算法受光照条件影响大、误识别多等问题，提出双阈值分割算法和以多目标跟踪为核心的算法框架。新的分割算法解决了行人亮度分布不均时的分割问题，同时在新的框架下可以综合多帧的处理结果进行综合判断，通过将基于支持向量机的识别算法和多目标跟踪算法的融合，降低了系统的计算量，且比一般的系统具有更高的识别率。 (At night the dynamic context of pedestrian detection segmentation algorithm affected by light conditions, and false identification of many other issues, the dual-threshold segmentation algorithm and a multi-target tracking algorithm as the core framework. New segmentation algorithm to solve the uneven distribution of brightness of pedestrians at the time of partition, while in the new framework of an integrated multi-frame can be the result of a comprehensive treatment of the judge, through the support vector machine-based recognition algorithms and multi-target tracking algorithm integration reducing system of calculating the volume, and than a typical system has a higher recognition rate.)

32位基于ARM微控制器STM32F101xx与STM32F103xx的固件函数库。该函数库是一个固件函数包， 它由程序、数据结构和宏组成，包括了微控制器所有外设的性能特征。该函数库还包括每一个外设的驱动 描述和应用实例。通过使用本固件函数库，无需深入掌握细节，用户也可以轻松应用每一个外设。因此， 使用本固态函数库可以大大减少用户的程序编写时间，进而降低开发成本。 为了节省开发时间和工作效 率，所以一般我们进行应用程序编写的过程中都会去使用芯片厂商提供的固件库像Nuvoton和TI都为他们 的32位产品制作了固件库，不过他们对固件库的称呼是库函数，其实实质都是一样的，里面大量采用结构 体，枚举和指针，能够比较方便快捷的帮助用户上手芯片，当然你觉得库函数没有达到你的要求你也可以 进行一定的修改，不过对于基本的应用库函数还是能够满足普通用户的需求的。这里我将记录我在MDK 环境下移植STM32F103xx系列的固件库的过程，其他产品线的固件库也基本都一样。(32-bit firmware library based on ARM microcontrollers STM32F101xx and STM32F103xx. The library is a firmware function package, It consists of programs, data structures, and macros that include the performance characteristics of all peripherals of the microcontroller. The library also includes drivers for each peripheral Description and application examples. By using this firmware library, users can easily apply each of the peripherals without having to master the details. therefore, The use of this solid-state library can greatly reduce the user s program preparation time, thereby reducing development costs. In order to save development time and work efficiency Rate, so we generally use the process of writing the application will be used to provide the chip vendor firmware library Nuvoton and TI are for them 32-bit products produced a firmware library, but they are called on the firmware library library function, in fact, are the same substance, which a large number of structures )
