The task of person re-identification is to identify a person of interest at any time or place. This is done by extracting the image feature and comparing the features. Images of the same person should have similar features and have small feature distances, while images of different persons have large feature distances. Given a queried image and a pile of candidate images, the image that has the smallest feature distance is identified as the same person as the queried image. The following table lists the ReID detection models supported by the Vitis AI Library.
