Sažetak
Digital raster images often need to be represented in higher and lower resolutions. Resampling of digital images is an essential part of image processing. The most efficient and sufficiently accurate image resampling technics can produce spurious oscillations near sharp transitions of color. To improve that, we introduce the tension splines applied dimension by dimension. The presented tension spline procedure provides an elegant solution to the im- age resampling by constructing a smooth approximation with sharp non-oscillatory resolution of discontinuities. The numerical results on real digital images are given to show effectiveness of the proposed algorithm.
