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 techniques can produce spurious oscillations near sharp transitions of color. To improve that, we use several techniques based on Chebyshev splines applied dimension by dimension. The main idea is to introduce smooth, shape preserving approximations, which produce sharp, non-oscillating image edges. To demonstrate the advantages of our algorithms, we compare them with other algorithms on real digital images.
