Abstract: As one of the biometrics which can be perceived unobtrusively at a distance, gait recognition gets more and more attention. Efficient gait representation is critical for gait recognition and information fusion methods are important alternative to improve the performance of gait recognition. We summarized the recent advances in gait recognition from the viewpoint of gait representation and gait information fusion methods. We also summarized the latest gait representation methods in detail and sums up the gait information fusion methods from three categories: multi-feature fusion,multi-view fusion and multi-biometric fusion. Furthermore, the development trend of gait recognition was analyzed.

Key words: Gait recognition, Gait representation, Information fusion
