Signal Reconstruction from Samples at Unknown Locations with Application to 2D Unknown View Tomography
Sheel Shah, Kaishva Shah, Karthik S. Gurumoorthy +1
It is well known that a band-limited signal can be reconstructed from its uniformly spaced samples if the sampling rate is sufficiently high. More recently, it has been proved that…

A new variational principle for the Euclidean distance function: Linear approach to the non-linear eikonal problem
Karthik S. Gurumoorthy, Anand Rangarajan
We present a fast convolution-based technique for computing an approximate, signed Euclidean distance function on a set of 2D and 3D grid locations. Instead of solving the non-…
