Abstract

The aim of this study is to explore a new image enhancement technique to enhance geological and structural features from magnetic data. This new image enhancement technique is based on monogenic signal decomposition and is able to decompose 2D magnetic signals into three primary attributes (amplitude, phase and orientation) and two secondary attributes (directional Hilbert and Riesz transforms). Although many magnetic attributes have been utilized to map subtle geologic features, these five particular attributes appear to add more valuable information to magnetic data interpretation.
