通过改进基于Haar-like特征和Adaboost的级联分类器，提出一种融合Haar-like特征和 HOG特征的道路车辆检测方法-By improving based on Haar-like features and Adaboost cascade classifier, presents a fusion of Haar-like features and characteristics of HOG road vehicle detection method

In this paper, we firstly construct a wide-band undersampling array, then present a novel frequency and direction of arrival (DOA) estimation method for a very wide frequency band (2-18GHz). Choosing a set of appropriate sampling frequencies and

UCS 1 903N 是三通道 LED 驱动控制专用电路，内部集成有 MCU 数字接口、数据锁存器、LED 高压驱 动等电路。通过外围 MCU 控制实现该芯片的单独辉度、级联控制实现户外大屏的彩色点阵发光控制。增 加了 S-Drive 驱动技术及增强接收技术，在不降低发送频率（800K）的情况下将点与点间的拉线距离延 长到 10 米以上（信号和电源线并行拉长线），而且可以任意个点 10 米线跨接，不受需要长线跨接的点 数限制。产品性能优良，质量可靠。-UCS 1 903 n is
