why it states +1 in the end? about cython_bbox HOT 5 CLOSED

Given a box (0,0,5,5). The pixels of width is (5 - 0 + 1) = 6

from cython_bbox.

As I understand it works approximately good with large boxes (>100px)

from cython_bbox.

A bit different from the length of a line in geometry. In Detectron2 the computation of area/length changed.

For large box the difference of the two computations is negligible.

I got it, you are right.
Thank you!

On the other hand, it is nowhere stated that this code works only with pixel-based coordinate system. My code uses coordinates normalized to the (1; 0) interval (in relation to the image width and height), and of course adding a casual 1 to the coordinates completely messes up the area being calculated.

(In my code, this library is buried under 2-3 layers of other libraries that I do not own, so to debug this +1 error took me several days)
