Comparative study of metrics for evaluation of object localisation by bounding boxes.

This paper deals with a comparative study of metrics allowing the evaluation of results provided by object localization algorithms. We particularly focus on localization by the bounding box representation. 26 metrics are studied in this paper. A protocol is presented for the creation of ground truths and synthetic results of localization algorithms. These synthetic results permit to simulate several inaccuracies (translation, scale errors... ) and to study the metrics behaviors face to the considered alterations. Finally, some conclusions and perspectives are given.
