Edge detection process of Qom salt dome gravity anomalies using hyperbolic tilt angle

In recent decade the edge detection procedure has been of great utility in the modeling and interpretation of self-potential, magnetic and gravity anomalies. This paper applies a precise edge detection procedure, called hyperbolic tilt angle (HTA) technique. The sufficiency of the HTA method is indicated using complex synthetic models and a residual gravity data set from Iran. Compared with the formal methods, the HTA filter more detailed outcomes for buried models and is less sensitive to noise.
