WebIn this video we show you how to evaluate the performance of your model by calculating mean Average Precision (mAP) WebAP [IoU = 0.50] and AP [IoU = 0.75] are reported, as well, since they are more common in the literature and results are more tightened. Loose thresholds are reported as well. Three models improve their performance with multiscale: GCNet, MS-RCNN, and Point_Rend. The best result overall was Mask-RCNN with AP [IoU = 0.50:0.95] with 0.671.

WebFaster R-CNN is an architecture for object detection achieving great results on most benchmark data sets.
