Özet
One of the most important aims of potential field geophysicists is
delineate the edges of subsurface structures. There are many methods
based on horizontal and vertical derivative of potential field data for
edge detection and enhancement. The structure tensor technique one of
the image processing techniques is used to edge detection studies inmany scientific areas. In this paper, the technique was
applied to potential field data and detected edges of the subsurface
lineaments using its eigenvalue analysis. Based on noise-free and noisy
synthetic data sets, the technique was tested and satisfactory results
were obtained. The proposed method was applied on two real potential
field datawhich are gravity data of Konya region and magnetic data of
Eastern Anatolia Region in Turkey. These examples demonstrate that the
technique provides beneficial information to geoscientists for
determining the horizontal location of subsurface structures such as
contacts, faults or various source bodies.
