p. 255-257

Résumé

– We use a new approach to combine magnetic and electrical geophysical data from two different archaeological areas in Greece (Europos & Doriskos).

– Using the curvelet transform we express the feature of the images as a function of spatial coordinates, scale, and orientation.

– A combined image is created in the curvelet domain through the objective selection of the most salient features.

– The results show several potential archaeological structures.

Introduction

Over the recent years, the use of geophysical methods has become a crucial part of the archaeological research, by accurately mapping near surface structures and identifying buried archaeological targets (e.g., Ernenwein & Hargrave, 2007; Gaffney, 2008). Moreover, it has become common nowadays to apply more than one geophysical method over the same area to investigate multiple properties of the subsurface. Inevitably, this has led to the requirement to jointly analyze and interpret overlapping dissimilar geophysical datasets. One promising approach for combining geophysical data taken using different methods, is the image fusion using multiscale signal analysis methods.

In this work we present the results of the application of the curvelet-transform-based fusion method in geophysical images, in two different areas of Greece; the archaeological area of Europos, in the Central Macedonia Region and the archaeological area of Doriskos, in Thrace.
