Spatial Domain Filter Design

چکیده
In this paper, we present both a methodology and a rationale for designing filters based on spatial smoothness and accuracy criteria. Frequency based methods have been used to design function and derivative reconstruction filters especially in image and signal processing. Desired filter characteristics are specified in terms of spectral properties. However, for visualization and image synthesis algorithms it is more natural to specify a filter in terms of the smoothness of the resulting reconstructed function and the spatial reconstruction error. Most currently known filter choices are limited to specific set of functions, and the visualization practitioner has so far no way to state his preferences in a convenient fashion.
