The Effect of Time on the Performance of Gait Biometrics
Many studies have shown that it is possible to recognize people by the way they walk. However, there are a number of covariate factors that affect recognition performance. The time between capturing the gallery and the probe has been reported to affect recognition the most. To date, no study has shown the isolated effect of time, irrespective of other covariates. Here the authors present the first principled study that examines the effect of elapsed time on gait recognition. Using empirical evidence they have shown for the first time that elapsed time does not affect recognition significantly in the short to medium term.
