The capture and dissemination of integrated 3D geospatial knowledge at the British Geological Survey using GSI3D software and methodology

The Geological Surveying and Investigation in 3 Dimensions (GSI3D) software tool and methodology has been developed over the last 15 years. Since 2001 this has been in cooperation with the British Geological Survey (BGS). To-date over a hundred BGS geologists have learned to use the software that is now routinely deployed in building systematic and commercial 3D geological models. The success of the GSI3D methodology and software is based on its intuitive design and the fact that it utilises exactly the same data and methods, albeit in digital forms, that geologists have been using for two centuries in order to make geological maps and cross-sections. The geologist constructs models based on a career of observation of geological phenomena, thereby incorporating tacit knowledge into the model. This knowledge capture is a key element to the GSI3D approach. In BGS GSI3D is part of a much wider set of systems and work processes that together make up the cyberinfrastructure of a modern geological survey. The GSI3D software is not yet designed to cope with bedrock structures in which individual stratigraphic surfaces are repeated or inverted, but the software is currently being extended by BGS to encompass these more complex geological scenarios. A further challenge for BGS is to enable its 3D geological models to become part of the semantic Web using GML application schema like GeoSciML. The biggest benefits of widely available systematic geological models will be an enhanced public understanding of the sub-surface in 3D, and the teaching of geoscience students.     

A Case Study: Management and Exploitation of the Nuclear Decommissioning Agency Geoscience Data Archive

The British Geological Survey (BGS) is responsible for managing a major geoscience data archive on behalf of the UK Nuclear Decommissioning Authority (NDA). Much of this geological data was captured during the 1990s and early 2000s using now obsolete software and data formats. This data asset remains an important resource for the NDA and the wider scientific community. The NDA wishes to ensure the data remain accessible and usable for many decades into the future. BGS has been working closely with Radioactive Waste Management (RWM), a wholly owned subsidiary of the NDA, on a program of data management and digital continuity measures to ensure the long-term usability of the data. This article describes some of the challenges and outlines the approaches we have taken to address these issues.

A Fast Search Algorithm for a Large Fuzzy Database

In this paper, we propose a fast search algorithm for a large fuzzy database that stores iris codes or data with a similar binary structure. The fuzzy nature of iris codes and their high dimensionality render many modern search algorithms, mainly relying on sorting and hashing, inadequate. The algorithm that is used in all current public deployments of iris recognition is based on a brute force exhaustive search through a database of iris codes, looking for a match that is close enough. Our new technique, Beacon Guided Search (BGS), tackles this problem by dispersing a multitude of ldquobeaconsrdquo in the search space. Despite random bit errors, iris codes from the same eye are more likely to collide with the same beacons than those from different eyes. By counting the number of collisions, BGS shrinks the search range dramatically with a negligible loss of precision. We evaluate this technique using 632,500 iris codes enrolled in the United Arab Emirates (UAE) border control system, showing a substantial improvement in search speed with a negligible loss of accuracy. In addition, we demonstrate that the empirical results match theoretical predictions.

Robust and efficient foreground analysis in complex surveillance videos

Mixture of Gaussians-based background subtraction (BGS) has been widely used for detecting moving objects in surveillance videos. It is very efficient and can update the background model with slow lighting changes, however, it suffers from a number of limitations in complex surveillance conditions such as quick lighting variations, heavy occlusion, foreground fragments, slow moving or stopped object etc. To address these issues, this paper first focuses on foreground analysis within the mixture of Gaussians BGS framework in long-term scene monitoring to handle (1) quick lighting changes, (2) static objects, (3) foreground fragments, (4) abandoned and removed objects, and (5) camera view changes. Then, we propose a framework with interactive mechanisms between BGS and processing from different high levels (i.e. region, frame, and tracking) to improve the accuracy of moving object detection and tracking to handle (1) objects that stop for a significant period of time and (2) slow-moving objects. The robustness and efficiency of the proposed mechanism are tested in IBM Smart Surveillance Solution on a variety of sequences, including standard datasets. The proposed method is very efficient and handles ten video streams in real-time on a 2GB Pentium IV machine with MMX optimization.
