Furthermore  CMOS sensors are the best choices for low-cost imaging systems. An image identification system based on CMOS image sensor is used to identify the seal images that include fingerprint  and then determine whether the seal is fake or not. The system consists of a color CMOS image sensor (OV2610)  a buffer memory  a CPLD  a MCU (P89C61X2)  a USB2.0 interface chip (ISP1581) and a personal computer. The CPLD implement the logic and timing of the system. The MCU and the USB2.0 interface chip deal with the communications between the images acquisition system and PC. Thus PC can send some parameters and commands to the images acquisition system and also read image data from it. The identification of the images of seal is processed by the PC. The structure and scheme of the system are discussed in detail in this paper. Several test images of seal taken by the system are also provided in the paper.   SCATTERING RATES OF WANNIER STATES IN SUPERLATTICES IN AN ELECTRIC-FIELD 期刊论文  OAI收割 physical review b, 1994, 卷号: 50, 期号: 20, 页码: 15067-15072 XIA JB 收藏  |  浏览/下载：16/0  |  提交时间：2010/11/15 NEGATIVE DIFFERENTIAL CONDUCTANCE  SEMICONDUCTOR SUPERLATTICES  GAAS/ALAS SUPERLATTICES  INDUCED LOCALIZATION  STARK LOCALIZATION  CONDUCTIVITY  QUANTIZATION  VELOCITY   WANNIER LOCALIZATION IN GAAS/GAALAS SUPERLATTICES UNDER ELECTRIC-FIELD 期刊论文  OAI收割 journal of applied physics, 1992, 卷号: 72, 期号: 7, 页码: 3209-3211 ZHANG YH; JIANG DS; LI F; ZHOU JM; MEI XB 收藏  |  浏览/下载：13/0  |  提交时间：2010/11/15 EXCITON STARK LADDER  SEMICONDUCTOR SUPERLATTICES  ABSORPTION-EDGE  BLUE SHIFT  QUANTIZATION
