Covariogram function algorithm:
Reconstructs an approximation to a regular polygon or an ellipse from a finite number of noisy
measurements of its covariogram function. See the section on Algorithms for more information.

Choose to reconstruct a regular polygon or an ellipse:  

Number of vertices of regular polygon 
Noise level (between 0 and 1) 

Noise level (between 0 and 1) 
Scale factor for the major axis (between 0 and 1) 
Scale factor for minor the axis (between 0 and 1) 
Rotation in radians (between 0 and π) 
*Please allow up to two minutes for reconstructions from a large number of measurements.
