Overview

PMACE: Projected Multi-Agent Consensus Equilibrium

A reconstruction \(x\) is subdivided into possibly overlapping components, \(v_j\), and distributed to multiple agents, \(F_j\), each of which acts to improve this local reconstruction. These local reconstructions are combined using a pixel-weighted averaging operator, \(G\), that reassembles the local components into a consistent global reconstruction.

Distributed Reconstruction and Application

Ptychography is an advanced computational imaging technique that can produce high-resolution images of nanoscale objects such as semiconductors and other manufactured nanomaterials. It works by moving a coherent X-ray probe across the object in overlapping patches and the far-field diffraction pattern associated with each scan position will be collected and used to recover the structure of the sample.
