I would like to compute mAP. I detect only 1 class.
I know should create two array. Presicion array and recall array and plot Precision/Recall Curve (PR Curve).



Max of Groud-truth bounding boxes: 4
Max of Prediction bounding boxes: 2



Should I compute AP for one image and then sum of the AP and divide by number of images?



I use MASK RCNN. Thank you in advance.
