We develop a new perspective invariant feature space representation of remotely sensed objects, regarding the features themselves as primitive observables of the 3D objects and to estimate them from multiple sensor measurements. This is formulated as an inverse problem in the feature coefficients. Once the coefficients are estimated they may be used to derive higher level features used by machine...
Some geophysical and geotechnical scientists would wish to non-invasively measure the electromagnetic properties of soils using inexpensive, even disposable, technology. They may even wish to develop inexpensive and compact low-power GPR equipment for such uses as teaching and mitigation of construction risks during excavation. To this end, a heuristic comparison is made between a commercial Vector...
Workshops were held at the GPR08 and IWAGPR09 conferences with the intention of developing closer links between GPR users and soil spectroscopy researchers, including developing an improved understanding of the associated research needs. Both workshops were well attended and provided a useful forum that identified elements central to greater interchange of information between the two disciplines....
Whereas overhead infrared imagery shows promise for detecting buried landmines, detection algorithms must deal with the daunting challenge of distinguishing between landmines and clutter objects which frequently possess similar spatial and spectral characteristics to landmines. However, groups of clutter features are rarely related spatially in the same way that groups of mines are related. For this...
