Deformable Conv Offset Sample

Problem

Sample a deformable convolution feature value at (y + offset_y, x + offset_x).

Use bilinear interpolation with the sample coordinates clamped to the feature bounds and round the result to 4 decimal places.

case 1

in: [[[1,2,3],[4,5,6],[7,8,9]],1,1,0,0]

expected: 5

case 2

in: [[[1,2,3],[4,5,6],[7,8,9]],1,1,0.5,0]

expected: 6.5

case 3

in: [[[1,2,3],[4,5,6],[7,8,9]],1,1,1,1]

expected: 9

case 4

in: [[[1,2,3],[4,5,6],[7,8,9]],1,1,5,0]

expected: 8
