摘要

在犯罪现场发现的血迹有助于估计犯罪过程中发生的事件。通过分析血迹模式重建犯罪现场有助于了解血腥事件。因此,必须通过血迹模式分析(BPA)对血迹进行分类,并准确估计当时发生的行为。在本研究中,我们通过创建一个原型分类模型,研究了使用机器学习和深度学习通过评估相应的血迹类型来确定与血迹数据相关的行动的潜力。根据基于外观的分类系统,血迹共有 14 种类型。在本研究中,我们测试了每种血迹数据对 Swing、Cessation 和 Impact 等三种血迹模式的分类潜力。实验结果表明,我们为所选血迹建立了原型分类模型,模型的准确率达到 80%。

A first step towards a machine learning-based framework for bloodstain classification in forensic science
Bloodstains found at a crime scene can help estimate the events that occurred during the crime. Reconstructing the crime scene by analyzing the bloodstain pattern contributes to understanding the bloody event. Therefore, it is essential to classify bloodstains through bloodstain pattern analysis (BPA) and accurately estimate the actions that took place at that time. In this study, we investigate the potential of using machine learning and deep learning to determine an action related to bloodstain data through the accessment of the corresponding bloodstain type by creating a prototype classification model. There are 14 types of bloodstain according to the classification system based on appearance. In this study, we test the classification potential of each bloodstain data for three bloodstain patterns such as Swing, Cessation, and Impact. Through experiments, it is shown that our prototype classification model for the selected bloodstains is developed and the accuracy of the resulting model is evaluated to be 80 %.
