Abstract:
Advances in Imaging and Electron Physics merges two long-running serials-Advances in Electronics and Electron Physics and Advances in Optical and Electron Microscopy. This series features extended articles on the physics of electron devices (especially semiconductor devices), particle optics at high and low energies, microlithography, image science and digital image processing, electromagnetic wave propagation, electron microscopy, and the computing methods used in all these domains.-Includes grey systems and grey information -Discusses Phase diversity -Recent developments in the imaging of magnetic domains -Explores stochastic deconvolution over groups.
