摘要
Abstract
All existing footstep-based personal identification research methods take acoustics parameters as features,for instance, Mel-Frequency Cepstral Coefficients (MFCC ) and spectrum envelope similarity degree etc.Their common shortcomings are the severe constrain and limitation at recognizing the footsteps of one person with different shoes or on different floors since they are sensitive to different acoustic mechanisms.The article proposes a novel footstep feature extraction method,which takes footstep duration and interval lengths as recognizable features and finally uses k-nn algorithm for recognition test.Experiment results elaborate that the method is effective at footstep personal identification while it is well adaptive to footsteps under different acoustic mechanisms.关键词
