From @fnands notebook A quick YOLOv7 Baseline | Kaggle
Several parameters are changed. Mainly resolution(512=>640)
From @fnands notebook A Quick YOLOv7 Baseline [Inference] | Kaggle
Revise the NMS code. Make it utilize the mask of the fold selected by NMS.
And, add post processing. Only the largest masks were retained.
