The authors discuss the use of iterative restoration algorithms for the removal of linear blurs
from photographic images that may also be assumed to be degraded by pointwise …

We present a novel blind deconvolution technique for the restoration of linearly degraded
images without explicit knowledge of either the original image or the point spread function …

One of the most intriguing questions in image processing is the problem of recovering the
desired or perfect image from a degraded version. In many instances one has the feeling …

This paper analyzes different techniques for the calibration of force balances for use in short-
duration impulse hypersonic facilities such as shock tunnels. The background to how …

The aim of the present paper is to give a general method allowing us to devise maximum-
likelihood multiplicative algorithms for inverse problems, and particularly for signal and …

Superresolution algorithms have demonstrated impressive image-restoration results in the
space domain. We consider the limits on superresolution performance in terms of usable …

Measurements have been made of the propulsive effect of supersonic combustion ramjets
incorporated into a simple axisymmetric model in a free piston shock tunnel. The nominal …

An iterative restoration algorithm for the solution of x in y= Hx has been described. For the
purpose of comparison, a general overview of the existing iterative techniques is given. For …

A combination of modelling and analysis techniques was used to design a six component
force balance. The balance was designed specifically for the measurement of impulsive …

A stress wave internal force balance for the High Enthalpy Shock Tunnel Göttingen (HEG) of
the German Aerospace Center (DLR) to measure lift, pitching moment and drag was …
