WebAug 11, 2016 · For each predicted bounding box and each ground truth bounding box the Intersection over Union (IoU) score is computed. IoU is the ratio of the overlapping areas of two bounding boxes to the sum of their areas. Using a user-defined IoU threshold (default 0.7), predicted bounding boxes can be designated as either true positives or false ... WebYou can define several anchor boxes, each for a different object size. Anchor boxes are fixed initial boundary box guesses. The network does not directly predict bounding boxes, but rather predicts the probabilities and refinements that correspond to the tiled anchor boxes. The network returns a unique set of predictions for every anchor box ...
