FAQ: LF image ordering

[chshin10]

We extract epipolar image stacks like this.
If you use your LF dataset, LF image ordering may be different, so be careful.

seq90d [76, 67, 58, 49, 40, 31, 22, 13, 4 ] --> image_stack_90d(dimension:NxNx9)
seq0d [36, 37, 38, 39, 40, 41, 42, 43, 44 ] --> image_stack_0d(dimension:NxNx9)
seq45d [72, 64, 56, 48, 40, 32, 24, 16, 8 ] --> image_stack_45d(dimension:NxNx9)
seqM45d [ 0, 10, 20, 30, 40, 50, 60, 70, 80 ] --> image_stack_minus45d(dimension:NxNx9)
