Model Regularization 2: Differencing across offset

We can similarly write the model residual corresponding to the model regularization operator which applies a difference with offset to each $\bold m_{i,k}$ at fixed t.  
\bold r_m^{[2]}(\tau,x,i) = m_{i,k}(\tau,x) - m_{i,k}(\tau,x+\Delta x).\end{displaymath} (6)
A similar approach is used by Prucha and Biondi (2002) to regularize prestack depth migration in the angle domain.
