Speculations on contouring sparse data: Gaussian curvature

Jon Claerbout and Sergey Fomel,


We speculate about regularizing (interpolating) sparse data. We speculate that L1 regularization would be desirable. An example convinces us it would not. Changing direction we learn that flexed paper has zero Gaussian curvature. Unfortunately, Gaussian curvature is a nonlinear function of the altitude.
