Implementing point cloud to grid conversion for digital elevation maps (DEM) presents one with many options for interpolation and we intend to explore algorithms for interpolation during the conversion process with a specific focus on Voronoi natural neighbor interpolation. By partitioning the environment into Voronoi cells and using the information from neighboring cells and their respective g...

Inverse solutions to interpolation techniques in computer graphics may increase the accuracy of the rendered frames. An example is the use of an arbitrary time stamp in time interpolation to evaluate the t-parameter, which in turn can be used for time-variant spatial interpolation. In this paper, an analytic inverse is presented for a shape-preserving piecewise cubic Hermite interpolant, used i...

In this paper the capacity of different interpolation techniques aimed at wow defect reduction is examined. Involved are: linear interpolation, two polynomial based interpolation methods (Hermite and spline) and the windowed sinc-based method. The performance of a synthetic audio signal restored using incommensurate resampling for wow cancellation is evaluated on the basis of standard audio def...
