Convex recovery of continuous domain piecewise constant images from non-uniform Fourier samples
Greg Ongie, Sampurna Biswas, Mathews Jacob
We consider the recovery of a continuous domain piecewise constant image from its non-uniform Fourier samples using a convex matrix completion algorithm. We assume the discontinuit…

Structured low-rank recovery of piecewise constant signals with performance guarantees
Greg Ongie, Sampurna Biswas, Mathews Jacob
We derive theoretical guarantees for the exact recovery of piecewise constant two-dimensional images from a minimal number of non-uniform Fourier samples using a convex matrix comp…
