Limited Annotations Object Detection Results

The 3D semantic instance prediction task involves detecting and segmenting the object in an 3D scan mesh.

Our evaluation ranks all methods according to the average precision for each class. We report the mean average precision AP at overlap 0.25 (AP 25%), overlap 0.5 (AP 50%), and over overlaps in the range [0.5:0.95:0.05] (AP). Note that multiple predictions of the same ground truth instance are penalized as false positives.

This table lists the benchmark results for the 3D object detection with limited annotations scenario.
