摘要/Abstract

摘要： 目的研究利用腭皱数字图像进行法医口腔学同一认定的可行性。方法在特定环境下获取腭皱的数字图像,通过腭皱数字图像识别系统对图像进行降噪、增强、分割、特征提取、边缘检测、信息匹配等处理,并结合Matlab软件的运用,记录匹配结果及每位操作者匹配所用的时间。结果从匹配结果来看,应用腭皱识别系统匹配的正确率较高,3名口腔医师匹配的正确率均达到100%,其余2名评估者分别出现1例及2例未匹配成功。从匹配所需时间来看,匹配速度较快,口腔医师所需时间最短。结论运用腭皱数字图像可以实现更快更准确的法医口腔学的同一认定,为法医学同一认定提供一种新的方法和途径。

Abstract: Objective To investigate the feasibility of forensic identification through digital imaging of the palatal rugae. Methods Digital images of the palatal rugae under a particular environment were collected. Rugae Image Identification System was used for collection, noise reduction, augmentation, segmentation, feature extraction, edge detection, and information matching, with each procedure having a corresponding algorithm. After Matlab processing, the matching achievement ratio and matching time of palatal rugae images were recorded. Results Three dentists obtained 100% accurate Results, one case and two cases were not matched respectively by the other two evaluators. Dentists completed computer processing of the images in the shortest time. Conclusion A more rapid and accurate method for forensic identification was successfully achieved through digital imaging of the palatal rugae. The study proposes a new method for forensic identification.
