Question about bbox coordinate system exceeding image width/height

[imguangkuo]

Hi,
I found that some bounding boxes in the dataset appear to exceed the corresponding image size if they are interpreted as pixel coordinates.

For example, one sample has:

If the bbox is interpreted as pixel coordinates, the x ccoordinates are outside the image width:

width = 543
x1 = 622
x2 = 656

It is the wrong bounding box!
Could you please clarify the coordinate system used for the ... annotation?

Thanks
