图像分析测定红麦硬度方法的研究

QUANTITATIVE DETERMINATION OF HARDNESS BY IMAGE ANALYSIS FOR RED WHEAT

本研究针对 4 0种红麦 ,测定了其抗粉碎硬度指数 ,以此表示其硬度 ;同时 ,在一定的条件下 ,使用扫描仪采集经不同方法处理的红麦的反射图像 ,分别对每种不同处理的红麦反射图像进行分析 ,获取色泽参数 ,将色泽参数与抗粉碎硬度指数线性回归。实验结果显示 ,对不同处理的红麦所获得的图像都有色泽特征参数 ,其相关性十分显著 (r为 0 .9以上 ,n =4 0 )。

THE PULVERIZING RESISTANCE INDEX (PRI) OF 40 KINDS OF RED WHEAT WERE DETERMINED AS HARDESS INDEX.UNDER CERTAIN CONDITIONS,THE IMAGES OF 40 KINDS OF RED WHEAT (RESPECTIVELY PROCESSED INTO INTEGRATED KERNEL,PEARLED KERNEL AND HALF KERMEL)WERE ACQUIRED IN REFECTING LIGHT AND ANALYZED IN RGB,CMYK,HIS,LAB AND GRAY FORMAT RESPECTIVELY.EXCELLENT CORRELATIVITY WAS OBTAINED BETWEEN EACH OPTIMUM COLOR PARAMETER AND PRI(R VALUES WERE OVER 0.9).
