摘  要:印油种类区分是法庭科学文件检验的重要一环,对印油进行种类鉴别在印章印文检验中具有重要意义。为研究无损高效区分光敏印油种类的方法,本文用50种不同品牌光敏印油的原始光谱数据,选择Resnet18、Resnet50、Resnet101这3种模型,以4∶1的比例确定训练集和测试集,对原始数据进行分类。结果表明,Resnet18分类算法对显微分光光谱数据区分的准确率最高,可达到92.81%,为深度学习算法在光敏印油区分领域的应用提供一定参考。The classification of printing oil is an important part in the field of forensic scientific document examination,and the classification of printing oil is of great significance in the examination of seal documents.In order to study the method of non-destructive and efficient classification of photosensitive printing oil types,the original spectral data of 50 different brands of photosensitive printing oil were taken as the control group,and three classification algorithms Resnet18,Resnet50 and Resnet101 were selected to determine the training set and test set at the ratio of 4:l,and the original data were classified.The results show that Resnet18 classification algorithm has the highest accuracy of distinguishing microspectral data,reaching 92.81%,which provides a certain reference for the application of deep learning algorithm in the field of photosensitive printing oil classification.
