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