摘　　要：本文分析图像滤波处理特点及其基本方法,初步研究基于SOPC的图像低层次处理的硬件化方法设计。对数字图像滤波方法进行对比分析和优化,用FPGA实现快速中值滤波算法;分析利用Sobel算子和系统级并行流水线进行图像边缘检测硬件电路设计的优点及可行性;采用基于系统级流水线的滤波器设计方法,用以优化平衡性能要求和设计大小的实际限制。由于采用的都是基本算术逻辑运算,完全能够保证处理的实时性。In this paper,we analyze the main ways of image filtering processing and the characteristics. And preliminary study the hardware design methods based on SOPC low-level image processing. Besides, we eompare and optimize the digital image filtering method,and implement the fast median algorithm in FPGA; Making analysis for advantages and feasibility in use of the Sobel operator and systemqevel parallel pipeline processor to design circuits; We use filters design method based on system level pipeline. It is used to optimize the balance and design restrictions on the size. Because of using the basic arithmetic logic operation,we are fully able to ensure real-time processing.
