Abstract

The embodiment of the invention discloses a gait feature extraction method and device and a computer readable storage medium, and the method comprises the steps: segmenting each frame of image in M frames of images into three image segments, obtaining a first image segment set, a second image segment set and a third image segment set, the M frames of images being continuous M frames of images in a first video, each frame of image in the first video comprises a first person, M is the number of images included in one gait cycle, and M is an integer greater than 1; performing first convolution calculation on the first image fragment set, the second image fragment set and the third image fragment set to obtain a first feature image set, a second feature image set and a third feature image set; splicing feature maps corresponding to the same frame of image in the first feature map set, the second feature map set and the third feature map set into a feature map to obtain a fourth feature map set; and performing attention mechanism processing on the fourth feature image set to obtain a first gait feature. According to the embodiment of the invention, the accuracy of gait feature extraction can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image recognition, and in particular, to a gait feature extraction method, device, and computer-readable storage medium. Background technique [0002] As people pay more and more attention to public safety issues, the application scope of video surveillance is getting wider and wider. Traditional identity feature extraction methods usually require the use of high-definition information such as face, iris, and fingerprints. When the shooting distance is long, the light is dark, or the human cooperation is impossible, the above-mentioned high-definition information cannot be obtained, so these identity feature extraction methods restricted. [0003] Gait is a physiological and behavioral biometric that describes a person's walking pattern. Gait feature extraction can perform feature extraction on people's walking posture to complete long-distance recognition. Currently, gait f...
