A

Shift0.png and ShiftR2.png optical flow:

Shift0.png and ShiftR2U5.png optical flow:

I had to weigh the kernel with a gaussian and increase the size of the window to avoid the "aperture" effect.

B

Shift0.png and ShiftR20.png optical flow:

Shift0.png and ShiftR40.png optical flow:

The algorithm falls apart the bigger the displacement.This is because LK cannot handle larger displacements.
