Single and multichannel sampling of bilevel polygons using exponential splines
In this paper we present a novel approach for sampling and reconstructing any K-sided convex and bilevel polygon with the use of exponential splines [1]. It will be shown that wit...

Contour line thinning and multigrid generation of raster-based digital elevation models
Thin plate spline interpolation is a widely used approach to generate a digital elevation model (DEM) from contour lines and scattered data. In practice, contour maps are scanned a...

Fast tracking of natural textures using fractal snakes
Abstract — The natural environments that robotic applications often encounter can present difficult problems for imagebased task execution. Prior efforts have used both grayscale...
