Biometric means the identification of persons by their traits or characteristics. We give in this study a simple survey and a general review of gait recognition based on a skeleton model for human identification of recent gait progresses. Every individual has features; therefore, a biometric means a unique feature of any person. The methods of the recognition currently, such as face recognition, iris recognition or fingerprint recognition based, require a physical contact or cooperative subject. So it is difficult to identify individuals by using these methods at a distance. However, gait as a feature of persons walk does not have these constraints. Gait is, in fact, a novel biometric feature. It attempts to distinguish people by the way of their walk. It has been increasingly taken the attentions of the research workers. Recent years, gait has become a hot topic in computer vision with great development accomplished.
