Table 4. IRS Outputs for Static Filter Illustrated
in Figure 10
Figure 10 illustrates the sequence for a bilinear resampling
of a 63
°
rotation. The starting point is translated +1 in the
Y-direction. A common rotation matrix might be:
dX/dU
0
= cos (a) = .6
dX/dV
0
= -sin (a) = -.8
dY/dU
0
= sin (a) = .8
dY/dV
0
= cos (a) = .6

However, we have included a linear compression factor of
5:1, and must accommodate the fact that each time u is incre-
mented, the start of the new walk is referenced to the END of
the previous walk. Given these corrections, the rotation
matrix becomes:
dX/dU
0
= 5cos(a) = 3
dX/dV
0
= 5sin(a) = -4
Kernel = 1
dY/dU
0
= 5sin(a) – FOV = 3
dY/dV
0
= 5cos(a) = 3
