Sparse Randomized Approximation of Normal Cycles
Allen Paul, Neill Campbell, Tony Shardlow
We extend our work for compression of currents and varifolds to a compression algorithm for the embedded normal cycles representation of shape, restricted to the constant normal ke…

Compression of Currents and Varifolds
Allen Paul, Neill Campbell, Tony Shardlow
We derive an algorithm for compression of the currents and varifolds representations of shapes, using ridge leverage score (RLS) sampling, and the theory of Nystrom approximation i…
