Parallel Technologies with Image Processing Using Inverse Filter

引用

Journal of Computer and Communications 2024年第1期12卷 110-119页

作者： Rahaf Alsharhan Areej Muheef yasmin Al Ibrahim Afnan Rayyani Yasir Alguwaifli College of Computer Science and Information Technology (CCSIT) Imam Abdulrahman Bin Faisal University (IAU) Dammam Saudi Arabia

Real-time capabilities and computational efficiency are provided by parallel image processing utilizing OpenMP. However, race conditions can affect the accuracy and reliability of the outcomes. This paper highlights the importance of addressing race conditions in parallel image processing, specifically focusing on color inverse filtering using OpenMP. We considered three solutions to solve race conditions, each with distinct characteristics: #pragma omp atomic: Protects individual memory operations for fine-grained control. #pragma omp critical: Protects entire code blocks for exclusive access. #pragma omp parallel sections reduction: Employs a reduction clause for safe aggregation of values across threads. Our findings show that the produced images were unaffected by race condition. However, it becomes evident that solving the race conditions in the code makes it significantly faster, especially when it is executed on multiple cores.

随着信息加密和网络计算机技术日趋成熟,科技正在推动全球经济的转型变革。虚拟货币的产生在此过程中又显得至关重要。虚拟货币方案在许多情况下便于对等网络交互绕过传统的中央结算所。虚拟货币及其关联技术(特别是基于区块链的分布式账本)正在迅速发展,其未来前景难以预测。虚拟货币带来了许多潜在益处,包括更快速、高效的支付和转账等,并将最终促进普惠金融。一些虚拟货币方案背后的分布式账本技术提供的潜在益处将远超虚拟货币本身。但是,虚拟货币的出现也引发了许多潜在风险,如成为洗钱、恐怖融资、偷税漏税和欺诈等犯罪的工具。虚拟货币虽然目前的规模仍非常有限,对现阶段货币政策实施产生的风险亦甚微,但随着新技术的广泛应用,其对金融稳定产生的影响会日益显现。有关虚拟货币的有效监管对策还处于起步阶段。虚拟货币的在国家层面跨越了不同机构的职责,并在全球范围内操作,其监管难度很大。并且,许多虚拟货币在传统金融系统之外运作,缺乏透明度,其操作过程更难以被监管。各国监管机构已开始着手应对这些挑战且方式各异。需要注意的是,国家主管部门需认真权衡监管方式,既要适当处置风险又不能扼杀创新。为了在国家层面推进发展进程和促进政策的完善,国际层面也应进行更多努力。随着经验的不断积累,可考虑提出国际标准和最优方法,为不同领域的最优监管对策提供指导,从而促进跨辖区的协调。也可在此类标准基础上,为一些领域设立跨国合作和协调的框架。

Credit Card Fraud Detection Using Machine Learning Techniques

引用

Journal of Computer and Communications 2024年第6期12卷 1-11页

作者： Ananya Sarker Must. Asma yasmin Md. Atikur Rahman Md. Harun Or Rashid Bristi Rani Roy Department of Computer Science and Engineering Bangladesh Army University of Engineering & Technology (BAUET) Natore Bangladesh

Credit card companies must be able to identify fraudulent credit card transactions so that clients are not charged for items they did not purchase. Previously, many machine learning approaches and classifiers were used to detect fraudulent transactions. However, because fraud patterns are always changing, it is becoming increasingly vital to investigate new frauds and develop the model based on the new patterns. The purpose of this research is to create a machine learning classifier that not only detects fraud but also detects legitimate transactions. As a result, the model should have excellent accuracy, precision, recall, and f1-score. As a result, we began with a large dataset in this study and used four machine learning classifiers: Support Vector Machine (SVM), Decision Tree, Naïve Bayes, and Random Forest. The random forest classifier scored 99.96% overall accuracy with the best precision, recall, f1-score, and Matthews correlation coefficient in the experiments.
