difference between detect and ddetect #522

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

WongKinYiu commented 6 days ago

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

ekthaliz commented 6 days ago

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?

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. :)
