Abstract

Embodiments of the present application provide an image retrieval method, device, device, and storage medium, wherein the first feature vector corresponding to the image set to be retrieved and the second feature vector corresponding to the base image set are determined; An index table of spatial distribution information of vectors; according to the first feature vector and the index table, an image matching the image set to be retrieved in the base library image set is retrieved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer vision communication, and relate to, but are not limited to, an image retrieval method, device, device, and storage medium. Background technique [0002] Pedestrian retrieval task refers to a query picture of a pedestrian, and it is necessary to find all pictures of the same person in a large-scale data set. To solve this problem is mainly to extract a feature vector for each pedestrian picture, and use this feature vector to distinguish different pedestrians. [0003] Usually, the test of pedestrian retrieval is carried out as follows: two image sets to be retrieved (probe) and base library image set (gallery) are given, and pictures of different people and corresponding identification numbers (Identity, ID) are recorded. During the test, each picture in the probe and gallery is extracted through the pedestrian retrieval network to extract the feature vector, and each vector i...
