what the meaning of normalized bounding box

I have read in a paper that the author normalized the bounding box in the frame.

what the meaning of normalizing the bounding box and what the benefits of this process.

Thanks in advance for your cooperation

Regards

Solution

  • You normalise bounding box, when you want it to refer to the same relative area in a different image with a different resolution.

    If you didn't do this and transferred the bounding box from one image to another one with a different resolution, it could be that your bounding box appears in a different place or is differently sized. Usually not what you want.
