Optimal Linear Interpolation of Images with Known Point Spread Function

The need for interpolation between pixels arises in many contexts. Kriging provides a general theory for optimal linear interpolation, which can be implemented and interpreted in either spatial or frequency domains. Of critical importance is knowledge of the autocorrelation function of the image at sub-pixel distances or, equivalently, the form of the spectrum near the Nyquist frequency. Althou...

Automated Image-Adaptive Point-Spread Function Estimation for Biological Imaging

Why are we interested in image restoration? The idea is to visualise the hearing organ in near-intact preparations with confocal microscopy. This is often made under image conditions far from optimal and this is where image restoration can be very useful, allowing one to increase the signal-to-noise ratio of the image by denoising and to increase their resolution by deconvolution. The problem s...

Point Spread Function Estimation for a Terahertz Imaging System

We present a method for estimating the point spread function of a terahertz imaging system designed to operate in reflection mode. The method is based on imaging phantoms with known geometry, which have patterns with sharp edges at all orientations. The point spread functions are obtained by a deconvolution technique in the Fourier domain. We validate our results by using the estimated point sp...

Simulation model based approach for long exposure atmospheric point spread function reconstruction for laser guide star multiconjugate adaptive optics.

This paper discusses an innovative simulation model based approach for long exposure atmospheric point spread function (PSF) reconstruction in the context of laser guide star (LGS) multiconjugate adaptive optics (MCAO). The approach is inspired from the classical scheme developed by Véran et al. [J. Opt. Soc. Am. A14, 3057 (1997)] and Flicker et al. [Astron. Astrophys.400, 1199 (2003)] and reco...
