I don't know. Was it photoshopped

For example, the coordinate of the top blue dot is (x, y). Then you could get its sampling location (\delta x, \delta y) from the offset feature map. The result (x + \delta x, y + \delta y) is plotted in the middle layer. Because it's 3x3 kernel, there are 9 points plotted in the middle layer.

The process is done again for the bottom (9 x 9) points.

The version is too old, is there a new version to implement
