1. A method comprising: processing first data indicative of a first image of a subsurface region of interest on a machine to generate second data indicative of a second image, the first image being derived from measurements of seismic waves propagating in a plurality of directions and the second image being generated by partitioning the first image based on the directions; processing the second data to determine a dip decomposition for each of the directions; and based on the dip decompositions and the directions, generating an angle domain common image gather.
