Fig. 1From: Robust visual tracking via samples rankingMost of existing tracking methods only require to tell positive samples from negative ones as shown by the left panel. However, this is not enough for the visual tracking task as it needs to filter out the one having the largest IoU with the ground truth. To overcome this problem, we propose to predict scores that are consistent with the ranking order in term of IoU with the ground truth as shown by the right panelBack to article page
