蛋壳 无损检测 支持向量机
2009/5/22
针对当前禽蛋蛋壳无损检测系统存在检测精度不高的问题，提出粗糙集和支持向量机相结合的方法进行分类器的设计。首先，基于粗糙集理论对特征参数集进行属性约简，在约简过程中，利用模糊C均值聚类算法对特征参数进行量化，并基于属性重要性的启发式搜索对条件属性进行约简；然后，在属性约简的基础上完成支持向量机分类器的训练，在训练过程中，通过交叉验证法对分类器模型参数进行了优化。实验结果表明该方法的分类准确率能够达到...
Eggshell crack detection based on acoustic impulse response and supervised pattern recognition
eggshell crack detection acoustic resonance supervised pattern recognition
2014/3/7
A system based on acoustic resonance was developed for eggshell crack detection. It was achieved by the analysis of the measured frequency response of eggshell excited with a light mechanism. The resp...
