Ground Penetrating Radar (GPR) is an effective and practical geophysical imaging tool, with a wide set of applications in geological mapping of subsurface information. This research study aims at determination of the geophysical parameter differences in the subsurface geological structures and construction of a 3D fracture model. GPR and resistivity methods were applied to detect the unstable t...

In the Oil and Gas industry, processing and visualizing 3D models is of paramount importance for making exploratory and production decisions. Hydrocarbons reservoirs are entities buried deep in the earth’s crust, and a simplified 3D geological model that mimics this environment is generated to run simulations and help understand geological and physical concepts. For the task of visually inspect...

This work presents a methodology for 3D modeling of lip motion in speech production and its application to lip tracking and visual speech animation. Firstly, a geometric modeling allows to create a 3D lip model from 30 control points for any lip shape. Secondly, a statistical analysis, performed on a set of 10 key shapes, generates a lip gesture coding with three articulatory-oriented parameter...

Abstract Cross sections carry information on the spatial distribution of rock strata and development geological structures, it is an important data source for three-dimensional (3D) modeling. However, interpretation mapping structures in by means manual are inefficient costly, performance varies greatly with experts’ ability experience. The objective this article to develop automatic recognitio...

Currently, visually described borehole samples are the primary input for large-scale 3D geological models of the subsurface, both when modelling architecture and composition. Cone penetration tests are rarely used and to a limited extent only. There are several reasons why it is of interest to utilize CPT data for geological and lithological modelling of the Dutch subsurface: 1) CPTs are more a...

Improved Geological Modeling and Dynamic Data Integration Using the Probability Perturbation Approach

In recent years, there has been a growing interest in computer graphics and geometric modeling in the ability to create and manipulate Seemingly Impossible Models (SIMs). Methods to create derivative work and modify drawings and paintings of SIMs made by artists were suggested. Similarly, 3D realization of SIMs of some of these drawings were also offered. In this work, we further explore the na...

Magnetic instruments such as cross-wing gradiometers, vertical gradiometers and full tensor SQUID magnetometers presented challenges for geological interpretation and geophysical inversion. In particular, the full tensor magnetometer presents many new challenges for an interpreter where only the vertical derivative of the vertical magnetic component presents a useful geological analogue for vis...
