Normalization in YOLO #6788

Open sensationTI opened 4 years ago

sensationTI commented 4 years ago

it looks like the bounding boxes in yolo are normalized since the values (x,y,w,h) are between 0 and 1. But what is the benefit of doing this over normalizing the input image?

yolo style of bounding boxes are very useful when it is required to resize image. there is no need to recalculate bboxes, they are scale invariant.
