Geophysics

This is my past life, so all this work is now dated. It covers mostly image processing and inversion

We developed a mathematical framework which allows for the analysis, processing and inversion of gravity and magnetic images, based on multiscale edges. These edges represent the main features in an image, and they are a significant aid in the visual analysis and interpretation of potential field images. Also, under restrictive but geologically reasonable assumptions, these edges have simple spatial relationships with the location of contacts between bodies of different density and/or susceptibility and can consequently be used in an inverse process to reconstruct approximate 3-D models of the underground geology
