【摘要】 随着图像处理技术和多媒体技术的广泛应用,为了不影响图像采集系统的速度,对总线传输速率的要求也越来越高。去除噪声同时还要保留图像信号的高频信息,系统采用并行算法设计思想设计改造现已有中值滤波方法,提出层叠中值滤波结构模块进行滤波,并基于PCI总线在数据传输的优点,利用PCI总线完成实时图像系统采集后数据传输,给出整个硬件构造方法,利用VHDL硬件开发语言在ALTERA的可编程整列(FPGA)上实现,说明系统的可行性。更多还原

【Abstract】 With the image processing technology and the extensive application of multimedia technology, in order not to affect the speed of image acquisition system, the bus transfer rates higher and higher demands. Removal of noise while retaining image signals in the high- frequency information, the system uses parallel algorithm design is now thinking of the design of median filtering method to stack median filter to filter module structure. Based on the PCI bus and data transmission in the advantages of using PCI bus to complete real-time image acquisition system after data transmission. Given the hardware structure, using VHDL hardware development ALTERA programmable language in the entire series (FPGA) on the realization of the feasibility of the system.更多还原
