By using the optimized covariance matrices to optimize the new regularized discriminant analysis ( RDA ), the correct classification rate is higher than that by the old RDA. 利用优化的协方差矩阵对正则化判别分析方法进行优化,其模式分类正确率有显著提高。
The classification performance of extracted features was tested by an index called correct classification rate. 以分类正确率为指标检验了提取特征的性能。
Result shows that the method is simple, convenient and practical and has high correct classification rate. 结果表明:判别方法简单方便,正确率高,具有较强实用性。
For training samples their correct classification rate is 100 %. 训练样本的分类正确率达100%。
It was shown by the result of discrimination analysis that the correct classification rate of wheat and weeds detection with the selected wavelength points achieved 97 %. 统计分析的结果表明:运用选定的特征波长点建立判别模型识别小麦和杂草的正确识别率达到了97%;
