Abstract

The present application provides a method and device for generating quadruple images, including: when there are no quadruple-generated images in the pedestrian re-identification data set, obtaining images of different pedestrians respectively to form a batch processing sample set; processing batch processing Each image in the sample set is used to obtain the similarity between the images; according to the calculated similarity between the images, the image with the smallest similarity between each image in the batch sample set and other images of pedestrians corresponding to each image is determined respectively. And the two images with the largest similarity between each image and other pedestrian images form a quadruple image of each image. Through the method and device for generating a quadruple image provided in the embodiments of the present application, the pedestrian recognition ability of the trained pedestrian re-identification model can be improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, and in particular, to a method and device for generating a quadruple image. Background technique [0002] At present, pedestrian re-identification technology is a technology that uses computer vision technology to judge whether a specific pedestrian exists in an image or video sequence. This technology is being widely used in intelligent video surveillance, intelligent security and other fields. In order to identify pedestrians, it is necessary to use the collected pedestrian re-identification dataset as a training set, train a pedestrian re-identification model through a neural network (Neural Network, NN), and perform pedestrian re-identification with the trained pedestrian re-identification model. [0003] In order to train the pedestrian re-identification model, generally four images are randomly selected from the pedestrian re-identification dataset as a quadruple. After ...
