Abstract

The invention discloses a target re-identification method, a network training method thereof and a related device. The method comprises the steps of obtaining a training image set, wherein the training image set comprises images of multiple targets, and each target at least corresponds to two styles of images; identifying each image in the training image set by using a target re-identification network to obtain an identification result of each image, the identification result comprising features of the image; obtaining loss of the target re-identification network based on the identification result, the loss comprises first distance loss, and the first distance loss is obtained based on the distance between features of different styles of images corresponding to the target; adjusting parameters of the target re-identification network based on the loss; and repeating the steps until the condition of stopping training is met. In this way, the target recognition performance of the target re-recognition network can be improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to a target re-identification method, its network training method, and related devices. Background technique [0002] Compared with the face recognition task with a fixed viewing angle, pedestrian re-identification is not limited by the face viewing angle, human body posture and camera viewing angle, and its recognition effect is relatively better and the application scenarios are wider. Therefore, object re-identification technology has achieved rapid development in recent years. [0003] Target re-identification technology aims to find specific targets from videos or images, and it has important application value in the fields of security, new retail and the Internet. The targets of target re-identification technology can be pedestrians, vehicles, etc. Generally, a target re-identification network is used to perform target recognition, for example, a pedestri...
