FPGA在实时图像预处理中的应用

The Application of FPGA on Real-Time Image Pretreatment Algorithm

实时图像处理通常需要巨大的数据吞吐量和运算量。因此专用的硬件或者多重处理技术的并行处理很必要。描述了一个基于现场可编程门阵列(FPGA)的灵活的可编程图像处理系统。FPGA特有的逻辑结构单元对实现实时图像处理来说有着先天的优势。在此,我们提出一个通用的实时图像处理模型,并在FPGA上实现了中值滤波算法,从而对采集的实时图像作预处理。

Real-time image processing usually requires enormous throughput rate and huge amount of operations.So the parallel processing of specialized hardware or multiprocessing are therefore indispensable.This paper describes a flexible programmable image processing system using field programmable gate array（FPGA）.The logic cell nature of current available for FPGA is most suitable for performing real-time image processing operations.Here,the paper provides a general model for real-time image processing,and application of FPGA on image pretreatment.
