Gait Analysis for Surveillance

Gait refers to the patterns of movements the limbs make when walking. Human gaits refer to the variety of ways in which an individual can move, either naturally or as a result of training. The gait of each individual is as unique as their voice. On the basis of this knowledge, Machine Learning (ML) algorithms have been developed for gait recognition. Computer Vision (CV) techniques have facilitated the development of a wide range of approaches for identifying people by their movements in videos using both natural biometric characteristics (the human skeleton, silhouette, changes during walking) and abstractions. A gait recognition system identifies the human body based on its shape and the way it moves. A machine-learning system can recognize a person even if their face is hidden, turned away from the camera, or concealed behind a mask. An algorithm analyzes a person's silhouette, height, speed, and walking pattern to identify him or her. Gait recognition technology acquires data from multiple sources, such as video cameras and motion sensors. Data from these sources are then processed by a number of algorithms. Gait is recognized, data is processed, contours and silhouettes are detected, and individual features are segmented, according to the algorithm. After this, the feature extraction algorithm takes effect - this is what differentiates one gait from another. There are many different algorithmic requirements, and these algorithms can vary. Some algorithms, for example, are designed to process video information, while others employ sensor data. Because each gait is distinct, the identification algorithms are always confronted with new data. The system will assess future data better if it detects more gait variants. Assume the program compares two gaits that are highly similar. The algorithms for pattern recognition and silhouette segmentation have been trained to separate the tiny details and enter them into the database. This enables for more accurate gait categorization and improved results in the future.
