Abstract

Abstract In the context of the rapid development of science and technology and the modernization of the legal system, criminal activities are becoming more and more intelligent and technological, which also puts forward higher requirements for criminal technology. The current criminal technology equipment is relatively backward, and the technical level is not high enough, resulting in a low utilization rate of trace material evidence extraction, which directly affects the role of criminal technology in the investigation and solving of cases. In recent years, fingerprint recognition algorithms and image edge detection algorithms have been widely used in various fields. This work studied the application of fingerprint image fuzzy edge recognition algorithm in criminal technology, in order to improve the level of criminal technology and the utilization rate of physical evidence extraction. The criminal technology system is upgraded and optimized by combining fingerprint recognition algorithm and image edge detection algorithm. And fuzzy theory is added to ensure the feasibility of the research. The experimental results show that the fuzzy edge recognition algorithm of fingerprint image can improve the level of criminal technology and the utilization rate of material evidence to a certain extent. The utilization rate is increased by 7.04%. The recognition accuracy of the fuzzy recognition method is also 13.2% higher than that of the methods in the literature.

指纹图像模糊边缘识别算法在刑事技术中的应用

摘要在科学技术快速发展和法制现代化的背景下，犯罪活动越来越智能化、技术化，这也对犯罪技术提出了更高的要求。目前刑事技术装备相对落后，技术水平不够高，导致痕迹物证提取利用率低，直接影响了刑事技术在侦查破案中的作用。近年来，指纹识别算法和图像边缘检测算法在各个领域得到了广泛的应用。本文研究了指纹图像模糊边缘识别算法在刑事技术中的应用，以提高刑事技术水平和物证提取的利用率。将指纹识别算法和图像边缘检测算法相结合，对犯罪技术系统进行升级优化。并加入模糊理论以保证研究的可行性。实验结果表明，指纹图像的模糊边缘识别算法可以在一定程度上提高犯罪技术水平和物证利用率。利用率提高了7.04%，模糊识别方法的识别准确率也比文献中的方法提高了13.2%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
