Abstract
Seismic data of a subterranean region is received by data processing apparatus. The seismic data includes multiple seismic data points. For each seismic data point, gradients are computed based on the received seismic data and a dip angle is computed based on the gradients for the each seismic data point. The dip angle is smoothed using anisotropic diffusion.
