Mathematical Theory of Computational Resolution Limit in Multi-dimensions
Ping Liu, Hai Zhang
Resolving a linear combination of point sources from their band-limited Fourier data is a fundamental problem in imaging and signal processing. With the incomplete Fourier data and…

A mathematical theory of computational resolution limit in one dimension
Ping Liu, Hai Zhang
Given an image generated by the convolution of point sources with a band-limited function, the deconvolution problem is to reconstruct the source number, positions, and amplitudes.…
