WebMay 6, 2024 · The offsets determine the sampling locations of the kernel at each point in the output map. This article explains it very well (especially the first image). For example a 3x3 deformable convolution on a (h, w) input has an “offset map” of (18, h, w). 18 because 9 x (x,y) coordinates for the sampling locations.. These offset maps are calculated with … WebApr 7, 2024 · In deformable convolution, the regular grid R is aug- mented with offsets {∆pn n = 1, ..., N }, where N = R . The output offset fields have the same spatial resolution with the input feature map. The channel dimension 2N corresponds to N 2D offsets." So, I think the shape of offset field would be [2*9, H, W] if 3x3 kernel is used.
