【摘要】 目的建立使用动态比对表检验步态等人像运动特征的具体方法,为人像同一性鉴定中的动态特征比对提供方法和依据。方法从视频采集、预处理、特征提取、识别判断等流程出发考察现有的步态自动识别方法,并依据人像鉴定的实际需求进行分析。结果动态比对表制作应当依照检材、样本采集、归一化处理和制作、标识与输出等步骤,并考虑步态周期、视频参数等制作细节。结论使用动态比对表对人像运动特征进行考察有助于特征的展示,能够成为鉴定人进行人像鉴定的有效辅助手段。更多还原

【Abstract】 Objective To establish a method based on dynamic comparison chart for human motion characteristics in forensic human image identification. Methods The automatic gait recognition method based on 4 steps, namely video capture,preprocessing, feature extraction and recognition, was studied and analyzed according to actual demands. A comparison chart was designed and tested. Results A method based on dynamic comparison chart was established by steps of sample capture,normalization processing, marking and output. Details such as gait cycle and parameters of the video were taken into consideration. Conclusion The method is efficient, and can be used for forensic human image identification.更多还原
