How to label negative samples (without any object)?

[brent88310070]

Hi everyone,

I have two questions about negative samples, which are defined as images without any objects.
My task involves many negative samples, and I need to determine whether the output is negative or not.

Question 1: Despite related issues before ( #38 ), I still can't figure out how DINO classifies negative samples.

Question 2: If DINO can classify negative samples, how should these samples be labeled ? Should all values be zero (e.g., label = 0, bbox = [0,0,0,0]) ?

Thanks a lot!

I have the same problem, I wonder if you have solved it. If possible, can we discuss it?
