Q$-4$ Consider $3$ bounding boxes box$1,$ box$2$ and box $3.$ Each bounding box is represented bycoordinates of top left and bottom right corners. Let g$=[3,12,11,3]$ be the ground truth.Box$1=[0,10,10,0]$Box$2=[5,15,15,5]$Box$3=[2,12,12,2]$Perform the following operationsa$)$Compute IoU between ground truth and other $3$ boxes. Select the best suitable box by choosingthreshold of your choice.b$)$ how to choose threshold for bounding box. Comment on the threshold you have chosen.
