Paper Abstract

Expert interpretation of raster-based data, needed when, for example, automatic reconstruction of sparsely sampled data cannot produce accurate models, requires a means for interaction through which the expert's knowledge can be incorporated into the model to improve accuracy. If such expert interpretation is to be viable, the interaction must be intuitive, direct and flexible. We present a novel approach to the design of such interaction: the use of the discrete thin-plate spline permits interactive manipulation of the stiffness and tension parameters in the plate to control the behavior between control points; an object based approach allows raster based objects to be manipulated in an intuitive manner in the context of a visual representation of the objects. The editor adopts a problem driven approach which allows specialized editing tools to be developed for editing in a specific application domain. A prototype implementation of the editor is presented which provides insights into the advantages and limitations of the approach.
