Defect image with transversal and longitudinal super-resolution achieved with two-measure adaptive extrapolation method
Creators
Description
Results of applying the method of two-measure adaptive extrapolation (modification of Hershberg-Papoulis algorithm) to achieve superresolution of defect images, reconstructed according to multifrequency acoustic digital holograms are considered. Increase of transversal and longitudinal resolutions by the factor of 4 and 2 respectively is obtained in experiments on processing images of point and volume defects. 17 refs., 4 figs., 1 tab
