Automated detection and classification of counterfeit banknotes using quantitative features captured by spectral-domain optical coherence tomography

Counterfeiting of banknotes is still a severe crime problem in many countries. One of the most significant issue for solving the crime is to classify the counterfeit types and identify the sources. Most of the current methods to classify counterfeit banknotes rely on manual examination that is time-consuming and labor-intensive. Moreover, these methods only detect surface features which can be easily imitated through advanced printing technology. In this study, an automated method based on optical coherence tomography (OCT) and machine-learning algorithms was proposed to classify different types of banknotes based on the internal features. A spectral-domain OCT (SD-OCT) system was employed for sub-surface imaging and quantitative assessment of banknotes. A total of 29 Chinese 100-Yuan banknotes were collected, in which 4 of them were real and 25 of them were counterfeiting by three different printing processes. Each banknote was imaged 10 times in 3 distinct regions, which resulted in a dataset of 290 samples. Each sample was characterized by extracting 2 A-scan (OCT signal intensity along depth) based features and 14B-scan (cross-sectional OCT images) based features. Several machine-learning models, including logistic regression (LR), support vector machines (SVM), K-nearest neighbor (KNN) and random forest (RF), were built and optimized as the classifiers that were trained using 203 samples and applied to predict 87 testing samples. The best performance was achieved by SVM classifier in which the sensitivity of 96.55% and specificity of 98.85% were obtained in discriminating between authentic and counterfeit banknotes, and the sensitivity of 94.67% and specificity of 98.22% were obtained in predicting the types of counterfeit banknotes. These classifiers were also evaluated using the receiver operating characteristic (ROC) curves. To the best of our knowledge, this is the first study where A-scan and B-scan derived features from OCT images have been used for the detection and classification of different types of counterfeit banknotes.

强化检察委员会司法属性之路径探析

在检察委员会的规范化建设已取得明显成效的情况下,应当更多地关注检察委员会的司法属性问题和决策机制的改革完善。检察委员会改革应遵循司法规律,将民主、高效、权威设定为基本目标,通过优化组织体系、改革决策模式、建立责任机制、提升委员司法能力等强化其司法属性。在决策模式改革上,应借鉴吸纳审判合议制和党委票决制的合理内核,保证委员的"民主"地位、严格检察长的"集中"机制,确立一级检察委员会定案机制,以此增强检察委员会决策机制的司法属性。     

全面建设小康社会新阶段统一战线的基本特征和工作指导原则

全面建设小康社会新阶段的统一战线工作,随着社会的发展发生了很多变化,表现出许多新的特征和内容。统一战线要在新阶段发挥新的、更大的作用,就要正视和总结这些新变化,适时地提出新的工作指导思想和指导原则。认真分析统一战线的自身特点和发展趋势,对于巩固和发展最广泛的爱国统一战线、实现中华民族的伟大复兴,有着十分重要的理论意义和实践意义。     

痕检技术实验教学如何体现公安特色

公安院校应正确理解公安教育痕检技术实验课的性质,针对目前各公安高校课程实置和实施的现状,结合公安实践中的需要,改革公安痕检技术实验课的教学模式,分类设置,实施多种教学方法,提高教学效果。     

论公安文明执法的时代性与人权意识的注入

公安文明执法是中国社会走向法治和步入全面建设小康社会的必然要求,具有鲜明的时代性。为适应我国建设法治社会的需要,公安执法应溶入现代法治理念,具有现代法治的品质和精神,彻底从过去阶级斗争的观念、运动式的模式中解放出来。而在这一变革过程中,必须对公安执法注入形成现代法治的理论基础———人权意识,洗涤传统的执法观念,根除错误的执法指导思想,这虽不是实现公安文明执法的全部,但却是公安执法创新的一个根本。
