Domain Adaptation for Person Re-identification on New Unlabeled Data

In the world where big data reigns and there is plenty of hardware prepared to gather a huge amount of non structured data, data acquisition is no longer a problem. Surveillance cameras are ubiquitous and they capture huge numbers of people walking across different scenes. However, extracting value from this data is challenging, specially for tasks that involve human images, such as face recognition and person re-identification. Annotation of this kind of data is a challenging and expensive task. In this work we propose a domain adaptation workflow to allow CNNs that were trained from one domain to be applied to another domain without the need for new annotation of the target data. Our results show that domain adaptation techniques really improve the performance of the CNN when applied in the target domain.
