摘　　要：在分析图像组成机理基础上,提出利用FGPA芯片通过相关运算检测图像相似度的设计方案。其方法是设置比较图像模板存储器MRAM、输入待比较图像FIFO存储器和输出相关结果存储器RRAM,通过对MRAM与滑动移入FIFO中各单元数据作相关运算,并将结果RRAM,然后对RRAM中的数据进行最大值和对称性分析,从而检测出两个图像的相似度。经ISE开发环境仿真测试,达到预定两图形相关与否的判定结果输出。On the basis of analyzing the mechanism of image composition,a design scheme of detecting image similarity by cor⁃relation operation using FGPA chip is proposed.The method is to set up a comparative image template memory MRAM,an input im⁃age FIFO memory and an output related result memory RRAM.By correlating the MRAM with the data of each unit sliding into FIFO,the result RRAM is calculated,and then the maximum value and symmetry of the data in RRAM are analyzed to detect the similarity between the two images.Through the simulation test of ISE development environment,the output of the decision result of whether the two graphs are correlated or not is achieved.
