Person re-identification (Re-ID) can be used to find the owner of lost luggage, to find suspects after a terrorist attack, or to fuse multiple sensors. Common state-of-the-art deep-learning technology performs well on a large public dataset but it does not generalize well to other environments, which makes it less suitable for practical applications. In this paper, we present and evaluate a new strategy for rapid Re-ID retraining to increase flexibility for deployment in new environments. In addition, we pay special attention to make our method work with anonymized data due to the sensitive nature of the collected data. A training set with anonymized snippets is automatically collected using additional cameras and person tracking. The evaluation results show that this rapid training approach obtains high performance scores.
