Exercise

Calculate NMS

Having extracted the predicted bounding boxes and scores from your object recognition model, your next task is to ensure that only the most accurate and non-overlapping predicted bounding boxes are retained by using the non-max suppression technique.

boxes and scores you created in the previous exercise are available in your workspace and torch and torchvision have been imported.

Instructions

100 XP
  • Import nms from torchvision.ops.
  • Set the IoU threshold to be equal 0.5.
  • Apply non-max suppression passing boxes, confidence_scores, and iou_threshold to the relevant function.
  • Use the output indices to filter predicted boxes.
