Seismic velocity estimation
What are some challenges in seismic imaging?The two main approaches to seismic imaging produce models for the underground velocities: the first is a process called time migration, which takes seismic data in time coordinates, and produces images and timemigration velocities, which are an averaged velocity of a particular type. The second, depth migration, takes seismic data in depth coordinates and produces seismic images in depth coordinates.
The inverse problemUltimately, we are faced with an inverse problem: Numerical algorithmsWe have done the following:
