Release of the challenge metric protocols and implementation

We released Open Images Challenge evaluation protocols on our website! Further, metric implementation for both tracks and data processing routines are now available as a part of Tensorflow Object Detection API.

Open Images Challenge evaluation protocol description is available here:

1. Object Detection Track evaluation protocol
2. Visual Relationships Detection Track evaluation protocol

We also provide implementation as a part of Tensorflow Object Detection API:

• Metrics description page
• A tutorial on object detection with Tensorflow Object Detection API.
