TLDR
A new computing method for discrete-signal interpolation suitable for use in image and signal processing and the synthesis of holograms is described, and is shown to be superior to the commonly used zero-padding interpolation method in terms of interpolation accuracy, flexibility, and computational complexity.Abstract:

Prolog to a chronology of interpolation: from ancient astronomy to modern signal and image processing
E. Meijering,H. Falk +1 more
TL;DR: A chronological overview of the developments in interpolation theory, from the earliest times to the present date, brings out the connections between the results obtained in different ages, thereby putting the techniques currently used in signal and image processing into historical perspective.

Edge Direction Preserving Image Zooming: A Mathematical and Numerical Analysis
François Malgouyres,F. Guichard +1 more
TL;DR: This paper focuses on linear methods, gives a general framework to design them, and shows that the preservation of 1D structures pleads in favor of the cancellation of the periodization of the image spectrum, and studies variational nonlinear methods.

Simulation of scanning transmission electron microscope images on desktop computers
TL;DR: Two independent strategies are presented for reducing the computation time of multislice simulations of scanning transmission electron microscope images: optimal probe sampling, and the use of desktop graphics processing units.

Real-time interferometric synthetic aperture microscopy
TL;DR: An interferometric synthetic aperture microscopy system design with real-time 2D cross-sectional processing that provides quantitatively meaningful structural information from previously indistinguishable scattering intensities and provides proof of feasibility for future real- time ISAM systems.
Journal ArticleDOI
Measurement of surface roughness by speckle correlation
TL;DR: In this paper, the authors measured the roughness of solid surfaces by digital speckle correlation of video signals and derived analytical relationships with numerical simulations that used two-dimensional arrays of random numbers with various maximum values representing the maximum surface roughness.
