3D Graphics & visualisation Geographical Information Systems

(GIS) This project is to create a cutting edge desktop/online system for building planning. The application will visualise in 3d new design proposals from any angle in real time. It will allow designs to be updated and reviewed rapidly by developers, planners, rights of light surveyors, historic building specialists, and related professionals revolutionising the way in which architectural designs are considered, dramatically speeding up and improving the early design and planning processes. Key research enabling this are:

• Capturing 3D raw data using digital aerial photographs / videos

• Filtering large scale data using

• build graphical model from this

• build relational spatial database for postcode

• 3D web presence

Application:

– Property industry – 3D gaming industry – 3D digital map provider – Environmental planning organization – Metropolitan Police – Insurance company

Projects:

– GMJ Design Ltd. – Foley Cooke Associates

Events:– International Conference Visualisation in

Built and Rural Environments– GeoAnalytics

Forensic / Survillance Digital Imaging

This project is to establish a frame work for possible future standards in CCTV imaging used in overt public domain based on the research trend such as:

• Optimal CCTV – number of camera requirement without compromising the standard.

• Frame rate – temporal attributes Vs. spatial and tonal resolution.

• Range vs. resolution constraint.• Image enhancement:• Multiple video frame• Non-uniform interpolation using local

shift vector• Brightness and colour correction• Zoom and rotate• Field alignment• Filters

Projects:

– Telnet Plc

Events:– Cgiv08 – FDI - Forensic Digital

Imaging

Design LanguageGeometric Patterns in Architecture

• Semantics of Icon & patterns in Architecture

• Geometric and Repeated patterns in Islamic Architecture - GIS

• Changing patterns across the cultures and Space and time

• Modeling these using Computer Graphics

• Test how the semantics of pattern by altering key attributes

Pixel Level Graphics ResearchSeries research projects that focus on the key attributes of image such as spatial, tonal and temporal domains which are the ingredients of any digital image. This research is fundamental to designing graphics tools and image processing software but also graphics hardware. The following are:

• Incremental Drawing algorithm

– Single-, double-, …n-level stepping– Square-, diagonal-move– Parametric or non-parametric approach– Rendering General Parametric Conic

Curves by using Taylor Series Approximation

• Anti-aliased curve rendering– General Rendering and Anti-aliasing

Algorithms for Conic Sections • Tonal, Spatial and temporal interchange-

ability for digital imaging
