To establish a deep-learning architecture based on faster region-based convolutional neural networks (Faster R-CNN) algorithm for detection and sorting of red ginseng ( et ) with internal defects automatically on an online X-ray machine vision system.
A Faster R-CNN based classifier was trained with around 20 000 samples with mean average precision value (mAP) of 0.95. A traditional image processing method based on feedforward neural network (FNN) obtained a bad performance with the accuracy, recall and specificity of 69.0%, 68.0%, and 70.0%, respectively. Therefore, the Faster R-CNN model was saved to evaluate the model performance on the defective red ginseng online sorting system.
An independent set of 2 000 red ginsengs were used to validate the performance of the Faster R-CNN based online sorting system in three parallel tests, achieving accuracy of 95.8%, 95.2% and 96.2%, respectively.
The overall results indicated that the proposed Faster R-CNN based classification model has great potential for non-destructive detection of red ginseng with internal defects.
基于更快的基于区域的卷积神经网络（Faster R-CNN）算法建立一种深度学习架构，用于在线X射线机器视觉系统上自动检测和分类有内部缺陷的红参。
使用约20000个样本训练基于Faster R-CNN的分类器，平均精度均值（mAP）为0.95。基于前馈神经网络（FNN）的传统图像处理方法性能不佳，准确率、召回率和特异性分别为69.0%、68.0%和70.0%。因此，保存Faster R-CNN模型以评估其在有缺陷红参在线分拣系统上的性能。
在三个平行测试中，使用一组独立的2000个红参来验证基于Faster R-CNN的在线分拣系统的性能，准确率分别达到95.8%、95.2%和96.2%。
总体结果表明，所提出的基于Faster R-CNN的分类模型在红参内部缺陷无损检测方面具有巨大潜力。
