1. A method comprising: processing first data representing a first image of a subsurface region of interest on a machine to partition the first image to generate second data representing a second image, wherein the first image is derived from measurements of seismic waves and the partitioning comprising partitioning the first image according to one of a source wavefield direction or a receiver wavefield direction without partitioning the first image according to the other of the source wavefield direction and the receiver wavefield direction; processing the second data to determine a dip decomposition for each of the directions associated with the partitioning; and based on the processing of the second data, generating an angle domain common image gather.
