摘要
图像滤波是图像预处理的重要部分,但由于滤波过程中需要处理的数据量较大,采用软件的方法难以满足实时性的要求。利用现场可编程门阵列(FPGA)的并行处理能力,提出了一种基于FPGA的快速中值滤波算法,相对与传统的中值滤波算法有较大的改进,减少了数据的比较次数,处理速度得到提高,并使用Matlab和Modelsim进行联合仿真,结果证明该算法滤波效果良好。
Image filtering is an important part of the image preprocessing.However,this process needs to deal with large amount of data,using software methods can not meet the requirements of real-time.Making use of parallel processing features of the field-programmable array,this paper proposed a new algorithm of median filter based on FPGA.There was a greatly improved in the processing speed,compared with the conventional median filter.The results show that the algorithm can achieve a good filtering effect.
