摘要

步态识别可以利用来自可穿戴设备的信号,例如智能设备中嵌入的加速度计。目前,这种识别主要用于主体验证:输入的探针只与系统图库中属于声称身份的模板进行比较。例如,有几项建议涉及对设备所有者的持续识别,以检测可能的盗窃或丢失。在这种情况下,假设图库模板获取和探测之间的时间很短是合理的。这项工作更倾向于研究更广泛应用的可行性,包括中长期识别(与整个系统图库进行比较)。第一项贡献是从步态信号中提取并分两阶段选择最相关的总体特征的程序。使用逻辑回归法为每个特征训练一个模型。第二个贡献是实验研究了步态模式在时间上的可变性的影响。特别是,当有更多的采集会话时,识别性能会受到将基准划分为训练集和测试集的影响,比如在利用的 ZJU-gaitacc 数据集中。当只有近时采集数据时,结果似乎表明重新识别(短时间采集)是这种识别最有前途的应用。完全使用不同的数据集进行训练和测试,可以更好地突出性状变异对测量性能的巨大影响。这就建议在智能环境智能的中长期应用中获取更多时段的注册数据。

User gait biometrics in smart ambient applications through wearable accelerometer signals: an analysis of the influence of training setup on recognition accuracy

Gait recognition can exploit the signals from wearables, e.g., the accelerometers embedded in smart devices. At present, this kind of recognition mostly underlies subject verification: the incoming probe is compared only with the templates in the system gallery that belong to the claimed identity. For instance, several proposals tackle the continuous recognition of the device owner to detect possible theft or loss. In this case, assuming a short time between the gallery template acquisition and the probe is reasonable. This work rather investigates the viability of a wider range of applications including identification (comparison with a whole system gallery) in the medium-long term. The first contribution is a procedure for extraction and two-phase selection of the most relevant aggregate features from a gait signal. A model is trained for each identity using Logistic Regression. The second contribution is the experiments investigating the effect of the variability of the gait pattern in time. In particular, the recognition performance is influenced by the benchmark partition into training and testing sets when more acquisition sessions are available, like in the exploited ZJU-gaitacc dataset. When close-in-time acquisition data is only available, the results seem to suggest re-identification (short time among captures) as the most promising application for this kind of recognition. The exclusive use of different dataset sessions for training and testing can rather better highlight the dramatic effect of trait variability on the measured performance. This suggests acquiring enrollment data in more sessions when the intended use is in medium-long term applications of smart ambient intelligence.
