Stacking angle-domain common-image gathers for normalization of illumination |

Fomel (2007a) defined the local similarity attribute using shaping regularization (Fomel, 2007b). The global correlation coefficient between two discrete signals and is defined as

where is a regularization operator designed to constrain the solution in a desired behavior, such as smoothness. Shaping regularization (Fomel, 2007b) can conveniently be applied in solving inverse problems (4) and (5) iteratively. The local similarity can smoothly measure the correlation between two signals locally. It is an estimate of waveform similarity of two seismic signals.
