腭皱法医学同一认定数字化系统的建立

目的建立腭皱法医学同一认定数字化系统并对其进行效果评价。方法在标准条件下获取腭皱的数字图像,对腭皱信息都进行采集、降噪、增强、分割、特征提取、边缘检测、信息匹配等处理,运用Matlab软件研制腭皱法医学同一认定系统,并进行效果评价。结果本研究成功建立腭皱法医学同一认定数字化系统,从匹配结果来看,正确率达到100%。结论腭皱法医学同一认定数字化系统的建立,为同一认定提供一种新的方法和途径。

The establishment of palatal rugae digitalization system on forensic identiifcation(

Objective To establish a digital system for forensic identiifcation of the palatal rugae and evaluate its application effects. Methods High-resolution digital images of the palatal rugae were harvested under the standard condition and processed including data collection, noise reduction, contrast enhancement, image segmentation, feature extraction, edge detection, and information matching. Apply an MATLAB software system to develop a digital system for forensic identiifcation of the palatal rugae ,and its application effects were evaluated. Results A digital system for forensic identification of the palatal rugae was successfully established. The digital system had an accuracy rate of 100%. Conclusion Establishing a digital system for forensic identiifcation of the palatal rugae provides a novel method for forensic identiifcation.
