The invention relates to an image re-recognition method and device, an electronic device and a storage medium. The method comprises the following steps: carrying out the feature extraction of a to-be-processed target contained in a to-be-processed image, obtaining a feature image of the to-be-processed target, carrying out the pooling of the feature image based on a plurality of pooling kernels of different sizes, and obtaining a pooling result of the to-be-processed target; collecting image features of the to-be-processed image; and after the image features of the reference image are determined, determining whether a to-be-processed target contained in the to-be-processed image is consistent with a reference target contained in the reference image according to the similarity between the image features of the to-be-processed image and the image features of the reference image. According to the method and the device, the problem that the accuracy of feature matching is still low under the condition that the scales of the targets in the recognized image are different in the prior art is solved, and the accuracy of re-recognition of the targets in the image is improved.
Description
technical field [0001] The present application relates to the technical field of image processing, in particular to an image re-identification method, device, electronic device and storage medium. Background technique [0002] Reidentification (ReID for short) is a problem of judging whether the objects recorded under different shooting devices are the same object. Specifically, re-identification uses deep neural networks, including operations such as convolution and pooling, to extract feature vectors of captured images, and then determine whether they are the same target based on the similarity between feature vectors. However, in the actual scene, due to the variety of scenes, the captured target image has problems such as illumination changes, angle changes, and mutual occlusion of targets, and even targets with extremely similar clothing in the target image, which in turn affects the accuracy of the feature vector extracted by the deep neural network. degrees, causing ...
