# Homework #1 : Panorama from multiple photographs

 The two images used for input with correspondence points.

 Gold standard with 4 points. Gold standard with 10 points. Gold standard with 20 points. Gold standard with 20 points and bilinear alpha falloff from image edges.

 Errors (normalized) 4 points 10 points 20 points DLT algebraic error 0 0.00004099 0.00004082 symmetric error 0 2.9866 2.8291 Normalized DLT algebraic error 0 0.0003945 0.0003971 symmetric error 0 2.9642 2.7994 Gold Standard Sampson error 0 .7277 0.6803 symmetric error 0 2.9558 2.7994

The normalized error table divides the total error by the number of points. Here we can see that increasing the number of points decreases the error. It is interesting that the normalized DLT yields a larger algebraic error, but the geometric error is less. That doesn't seem right.
