Abstract

The invention discloses a gait recognition method based on deep learning. The gait recognition method based on deep learning is characterized that identity of a person in a video is recognized according to gaits of the person through weight-shared two-channel convolutional neural networks by utilizing strong learning ability of the convolutional neural networks in a deep learning mode. The method has strong robustness on gait changes crossing large view angles, effectively solves the problem that accuracy is low when existing gait recognition technologies are used for recognizing gaits crossing view angles. The method can be widely applied to scenes with video monitoring, such as safety monitoring in airports and supermarkets, personnel recognition and criminal detection.

Description

Technical field [0001] The invention relates to computer vision and pattern recognition, and in particular to a gait recognition method based on deep learning. Background technique [0002] Among gait recognition methods, a common method is to first obtain a person's outline from all video sequences, calculate its gait energy image (GEI), and then compare the differences between different gait energy images. Similarity, and finally matching through a nearest neighbor classifier. However, previous methods are difficult to achieve practical accuracy when encountering serious cross-view problems. [0003] Deep learning theory has achieved very good results in the fields of speech recognition, image target classification and detection, etc. In particular, deep convolutional neural networks have very strong autonomous learning capabilities and a high degree of nonlinear mapping, which provides a good foundation for designing complex and high-precision systems. Classification mo...
