Previous: Conclusions
The tomographic operator we derive can potentially produce superior results to the operators based on oneway wave equation since it can capture wave paths with more accuracy. So, the next step is to test the migration velocity estimation results on a complex synthetic model, where oneway propagation operators fail and measure the amount of improvement. Then, the velocity estimation process should be tested on a real dataset.
Finally, since this method is very computationally intensive, it is crucial to adapt it on accelerated and parallel processing units such as GPUs. This is especially attractive since GPUs are particularly efficient for finitedifferencebased convolution algorithms such as propagation in time domain.
