Accurate horizontal boundary definition is essential in geophysical exploration, as it helps delineate subsurface formations and understand tectonic activities. Traditional boundary determination methods often face challenges in resolution and accuracy, necessitating the development of improved techniques. Recently, a range of edge detection techniques has been developed based on derivatives of the field. This study compares the performance of several recently developed edge identification methods, including improvised logistics of the total horizontal gradient, improvised tilt angle of the horizontal gradient, enhanced version of the horizontal tilt angle, the total horizontal gradient of ImpTDX, Gompertz function, and improved edge detector. These methods are evaluated using synthetic models and Bouguer gravity data from the Tuan Giao area, Vietnam. The results showed that the regional structures tend mainly in the NW-SE direction, and some structures in the NE-SW direction.
