Traveltime picking is an important step in seismic data processing, and it plays an important role in tomographic imaging. In this paper, we discuss a structure-enhanced high-dimensional time-frequency analysis algorithms for automatic traveltime picking based on instantaneous traveltime. By using a high-dimensional time-frequency transform operator that depends on prior structure information, the improved method introduces the lateral continuity of the recorded data and picks up the traveltime automatically. Testing this approach on field seismic data reveals its properties and shows it can accurately do the automatic seismic events picking.
