Seismic horizon mapping is an important step in seismic interpretation. Automatic tracking algorithms are valuable tools since manual mapping can be an extremely tiring and time consuming task. In the present work, we propose a new tracking algorithm for 2D seismic horizons based on shortest paths in Directed Acyclic Graphs. Our approach was designed to(More)
This paper presents a method to track horizons in a seismic section by maximizing a cost-function that measures the similarity between the seed and the tracked samples. The dynamic programming shortest-path algorithm is used to compute in linear time the optimal path between two given picks. Tests showed satisfactory results, since horizons were correctly(More)
— What do we find in common among systems that seek to convey meaningful images to an oil reservoir interpreter, a medical doctor and an ordinary sports fan enjoying a broadcasted game on TV? They are generated by a system that processes captured signals and produces images conveying relevant information to the viewer. These processes are based on Computer(More)
