WebNov 2, 2024 · Periodicity detection is an essential step for vision-based gait recognition. Unlike other biometric techniques, it is not suitable to use a single image of the silhouette for gait recognition because of the wobble of the body in walking. Thus, the input of gait recognition is a video sequence rather than a gait silhouette. WebNov 6, 2024 · Periodicity is prevalent in physical world, and many events involve more than one periods, eg individual's mobility, tide pattern, and massive transportation utilization. Knowing the true periods of events can benefit a number of applications, such as traffic prediction, time-aware recommendation and advertisement, and anomaly detection.
