Building surfaces of evolution: The Weaving Wall

摘要

This paper describes a three-dimensional surface-construction process designed for the analysis of image sequences. Named the Weaving Wall, the process operates over images as they arrive from a sensor, knitting together, along a parallel frontier, connected descriptions of images as they evolve over time. Although the Weaving Wall was developed to support a tracking mechanism for recovering the three-dimensional structure of a scene being traversed, other applications of the surface-building process have since become apparent. These include rendering and computation on tomographic medical data, display of higher-dimensional analytic functions, edge detection on the scale-space surface, and display and analysis of material fracture data. More generally, the Weaving Wall may be of use in representing the evolution of any two-dimensional imagery varying in a nearly continuous manner along a third dimension. We are currently looking into extending the processing to higher dimensions.
