hello,is it useful to use dcn on 1x1conv?

I would expect less effect on 1x1conv, simply because 1x1 conv is not doing much feature aggregation. Deformable conv helps mostly with dynamic feature aggregation. But still it would be interesting to see the results.

Yes, from my experimental results, there is only a little increase, but there is no comparison, so I don't know whether my result is normal

Good to know!
