Abstract:
The main contributions of this work can be summarised as: • Presenting a collection of hypotheses that will form the backbone, underpinning the motivation for work conducted within the field of video visualisation. • Presenting a prototype system to demonstrate the technical feasibility of video visualisation within a surveillance context, along with detailing its generic pipeline. • Provide an investigation into video visualisation, offering a general solution by utilising volume visualisation techniques, such as spatial and opacity transfer functions. • Providing the first set of evidence to support some of the presented hypotheses. • Demonstrating both stream and hardware-based rendering in the context of video visualisation. • Incorporating and evaluating a collection of change detection (CD) metrics, concerning their ability to produce effective video visualisations. • Presenting a novel investigation into interaction control protocols within multi-user and multi-camera environments. Video datasets are a type of volume dataset and treated as such, allowing ray-traced rendering and advanced volume modelling techniques to be applied to the video. It is shown how the interweaving of image processing and volume visualisation techniques can be used to create effective visualisations to aid the human vision system in the interpretation of video based content and features. Through the application of CD methodologies, it is shown how feature volumes are created and rendered to show temporal variations within a period.
