Drawing box around object to train, tight border or loose? #3999

When drawing boxes around the objects that you wish to detect, is it better to draw the box as close to the object boundaries as possible or leave a little gap?

For example, let's say my object is a square and is on a white background. Is it better to draw the box around the square with a little white border or should I draw it as tight as possible?

I added to readme: https://github.com/AlexeyAB/darknet#how-to-improve-object-detection

What is the best way to mark objects: label only the visible part of the object, or label the visible and overlapped part of the object, or label a little more than the entire object (with a little gap)? Mark as you like - how would you like it to be detected.
