GNGTS 2014 S essione 3.1 7×7 frequency slice size), and to calculate the Signal to Noise Ratio of the recovered data in time domain. Results are showed in Fig. 3. As it was easy to guess, the reconstruction quality decreases as the percentage of censored traces increases, maintaining acceptable values even with high number of missing traces. Fig. 1 - Results obtained on a portion of data with presence of linear events. Subset of synthetic data with 50% of missing traces (left), interpolation result obtained by OR1TP algorithm (right). Fig. 2 - Results obtained on a portion of data with presence of hyperbolic events. Subset of synthetic data with 50% of missing traces (left), interpolation result obtained by OR1TP algorithm (right). Fig. 3 - Quality reconstruction obtained for 5×5 and 7×7 frequency slice size, varying the number of random censored traces of the 3D data. The quality measure is the Signal to Noise Ratio (SNR) in dB.
