  • Publication number: 20220101644
    Abstract: A method and apparatus for pedestrian re-identification, an electronic device, and a computer-readable storage medium are provided. The method includes that: a pedestrian image to be detected is acquired; global feature information of the pedestrian image to be detected is extracted through multiple convolutional layers of a convolutional neural network; multiple pieces of intermediate feature information of the pedestrian image to be detected are extracted through the multiple convolutional layers of the convolutional neural network respectively, and the multiple pieces of intermediate feature information are merged as local feature information; and the global feature information and the local feature information are assigned as a classification feature of the pedestrian image to be detected, and a classification result of the pedestrian image to be detected is determined according to the classification feature.
