Intersection over Union with smoothing for bounding box regression

1 code implementation27 Mar 2023 Petra Števuliáková, Petr Hurtik

The main principle is adding a smoothing part to the original IoU, where the smoothing part is given by a linear space with values that increases from the ground truth bounding box to the border of the input image, and thus covers the whole spatial search space.
