The biometric gait recognition system has attracted much attention in the computer vision community because of its discreet recognition advantage in relatively distant locations. The present study provides a comprehensive overview of recent developments in approaches to detecting walking. The survey focuses on three main themes of a general walk-detection system, namely the appearance of the image of walking, the reduction in the dimensionality of features, and the classification of walking, and in addition, a review of the available records or datasets for the public to process the gait reorganization using different methods and calcifications. The final discussions describe a series of research challenges and give promising pointers for the future on the ground.
