Abstract
A method of performing person re-identification for images captured by at least two camera pairs operating with different environmental factors. Descriptors representing characteristics of objects corresponding to a person in the images are clustered. A probability distribution of the clustered descriptors is determined. A coupling map for the images is determined based on the probability distribution. A cross-correlation between at least two of the coupling maps is determined. A similarity of the images captured by the camera pairs is determined according to the cross-correlation. Person re-identification is performed for the different environmental factors using the descriptors, based on the determined similarity.
