difference between detect and ddetect

What is the difference between "detect" and "ddetect"? What does "d" mean?

[WongKinYiu]

detect decouple cls and reg, ddetect decouple cls, l, t, r, and b.

[ekthaliz]

detect decouple cls and reg, ddetect decouple cls, l, t, r, and b.

Thank you :)

Hello, I have one more question.
I think the meaning of ddetect is the use of group convolution.
It seems that the groups are convolved into four groups: left, top, right, and bottom.
What I'm curious about is, does group convolution have a greater effect than decouple in detect?
If so, how much more effective did you use it?

[WongKinYiu]

if each branch has same channel, group convolution is equivalent to branch decoupling.

Thank you for answer.
However, I was asking about the performance difference between the two methods.
I would like to know if ddetect decouple had better effect than ddetect decouple, such as mAP, speed, etc.
I would appreciate it if you could answer this. :)
