The above picture is transformed by a geometric transformation. The (forward) description of this transformation is:
The pixel at coordinate (x, y) in the original picture moves to the location (6 − 3y, 6 − 2x) in the
new picture.
A.
Compute the transformed image using Nearest-Neighbor interpolation over the 2×2 window specified below:
x = 0 x = 1
y = 0
y = 1
B.
Compute the transformed image using Bilinear interpolation over the 2 × 2 window specified below:
x = 0 x = 1
y = 0
y = 1
