 ## Updates
+
+2022/07/13 - Added a script with a simple example for computing the ADD and ADD-S metric on data. Please refer to [script/metrics/](https://github.com/NVlabs/Deep_Object_Pose/tree/master/scripts/metrics). 
+
 2022/03/30 - Update on the NViSII script to handle [symmetrical objects](https://github.com/NVlabs/Deep_Object_Pose/tree/master/scripts/nvisii_data_gen#handling-objects-with-symmetries).  Also the NViSII script is compatible with the original training script. Thanks to Martin Günther. 
 
 2021/12/13 - Added a NViSII script to generate synthetic data for training DOPE. See this [readme](https://github.com/NVlabs/Deep_Object_Pose/tree/master/scripts/nvisii_data_gen) for more details. We also added the update training and inference (without ROS) scripts for the NViSII paper [here](https://github.com/NVlabs/Deep_Object_Pose/tree/master/scripts/train2).
