Example evaluation from the NeonTreeEvaluation R package.
Predicted boxes (see below) in red and ground truth boxes are in black. In this image there are 10 image-annotated boxes, and 9 predictions. Each prediction matches an image-annotated box with an intersection-over-union score of greater than 0.4. This leads to a recall score of 0.9 and a precision score of 1.
