### Assigment 4 - Problem 3

Finally, check the correctness by verifying that the epipolar constraints are satisfied (up to a small residual) for all pairs of corresponding points.
what is 'a small residual', up to which value is it correct?

Hm... I'm getting values like 0.0696, -0.8719, -0.0788, -0.2702, -0.3713, -0.1788, -0.0099, -0.0553.

Do you have similar results or are these values too high?

my highest for this task is about 0.136 and i dont have any minus values here, but doesn't matter, only absolute value counts.

The values that I got look like

1.0e-03 *

0.2332
0.9369
0.0898
0.1669
0.4917
0.1868
0.0003
0.0397

But NO guarantee of the correctness. -_-b

I do not know how small a "correct" residual should be, as its value depends on a few factors (eg, distribution of 8 points, etc.).
