Abstract

The invention discloses a large space depth metric learning based gait recognition method. The large space depth metric learning based gait recognition method is characterized by comprising a trainingstage and a recognition stage; the training stage adopts a gait energy image to describe a gait sequence, a convolutional neural network is trained through a large space depth metric learning model,the convolutional neural network is taken as a feature extracting function in the recognition stage, the optimized gait feature is extracted from the gait energy image, and the identity of a gait person is recognized through nearest neighbor classifier. The gait recognition extracts the discriminative gait feature through the large space depth metric learning model, and the gait feature is matchedand recognized through similarity calculation. The large space depth metric learning based gait recognition method can be applied to various fields like intelligent video monitoring and intelligent vision robots, and has a broad application prospect.

Description

technical field [0001] The invention relates to a gait recognition method based on large-spacing depth metric learning, and belongs to the technical field of pattern recognition. Background technique [0002] Gait recognition, which determines identity through the way humans walk, has recently received increasing attention. Compared with other biometrics (such as face, iris, fingerprints), gait has some important advantages: 1) It is more suitable for long-distance Recognition, especially when other creatures are occluded or the resolution is too low; 2) It is difficult to imitate or camouflage, because this is a long-term human behavior; 3) A better recognition effect can be achieved without the cooperation of the user. These characteristics make gait very suitable for the field of intelligent video surveillance for security protection. [0003] In recent years, a large number of gait recognition methods have been proposed, which can generally be divided into two categorie...
