Abstract: The present disclosure provides a method and an apparatus for object re-identification, capable of solving the problem in the related art associated with inefficiency and low accuracy of object re-identification based on multiple frames of images. The method includes, for each pair of objects: selecting one of a set of images associated with each of the pair of objects, to constitute a pair of current images for the pair of objects; inputting the pair of current images to a preconfigured feature extraction network, to obtain feature information for the pair of current images; determining whether the pair of objects are one and the same object based on the feature information for the pair of current images and feature information for one or more pairs of historical images for the pair of objects by using a preconfigured re-identification network; and outputting a determination result of said determining when the determination result is that the pair of objects are one and the same object or that the pair of objects are not one and the same object, or repeating the above steps using the pair of current images as a pair of historical images for the pair of objects when the determination result is that it is uncertain whether the pair of objects are one and the same object. With the solutions according to the present disclosure, the speed and efficiency of the object re-identification can be improved.
