Model-based restoration of vibrated images with geometry-free tomography: in-vessel viewing with the ITER European Home Team's probe
Peter Jakubik · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
A novel approach to restoration of strongly vibrated images is described. The technique uses geometry free tomography method to formulate the task and the Theory of Convex Projections to restore the image. For the restoration no other information is used than the vibrated image itself and the model of the vibration. Subsequently it is shown that the parameters of the vibration model could be easily estimated. The paper emphasizes the insight to the problem as well as describes numerical experiments showing superb performance of the method applied to an international project of designing fusion reactors. It also can be applied to other complex tasks where the need of an acceptable visual observation is higher than the level of the technically available or economically justified potentialities, as in space robotics, machine hand eye coordination, vehicle guidance, mid-flight aircraft refueling, etc.
