Overview

This is the official evaluation server for ActivityNet-Entities dataset on the object localization task. ActivityNet-Entities is based on the video description dataset ActivityNet Captions and augments it with 158k bounding box annotations, each grounding a noun phrase (NP). More details please see our dataset repo, code repo, and CVPR 2019 oral paper.

Evaluation

Please read Section 5.1 Metrics and Section A.2 in the paper regarding details about each of the 7 metrics (localization accuracy, F1_all, precision_all, recall_all, F1_loc, precision_loc, and recall_loc). We use the same eval script as in the ANet-Entities dataset repo. Please read the Phases Tab to see the result submission instructions. You can submit results on GT sentences only, on generated sentences only, or both.
