In this thesis, I refer to data space as the un-migrated space. This means data
as a function of time. I consider two main sets of data: source gathers and CMP
gathers. The first are function of the source coordinates, offsets and time while
the second are function of the CMP coordinates, half-offsets and time.
I will refer to image space as the domain of migrated data. In particular, data
migrated in depth. In image space I consider two main datasets: Subsurface
Offset Common Image Gathers (SODCIGs) and Angle Domain Common Image Gathers (ADCIGs).
In this thesis I will use exclusively wave-equation migration algorithms.
