Abstract: As a new technology of biometrics,gait recognition has attracted a great of interest in computer vision community due to its advantage of unobtrusive recognition at a distance. In this paper, the general process of gait recognition was described firstly. Then the paper reviewed most existing typical methods for gait recognition and analysed their respective pros and cons. In addition, challenges that constrain practical application of gait recognition systems were discussed and more than 10 publically available datasets and experimental results of some typical methods were reported.Finally,future trends were given to guide further research in this field.

Key words: Gait recognition, Feature extraction, Performance evaluation, Progress
