Bounding box loss function
WebI'm working on regressing bounding boxes on images. Therefore I'd like to define a loss function that gives a higher penalty if the predicted values are outside of the bounding … WebMar 12, 2024 · But for a small bounding box, the loss will not be as large. So what they do is to take the square root to make sure we prioritise smaller bounding boxes equally as much as we do for large bounding boxes. Taking square root before square reduces the loss impacts due to the bounding box sizes. Share Cite Improve this answer Follow
