Abstract
A nonlinear method for image interpolation is presented based on spatial domain directional interpolation. Existing directional interpolation algorithms, which only consider edge regions, are extended to the whole image by interpolating in multiple directions. The interpolated values along various directions are combined using directional weights, which depend on the variation in that direction. The interpolation value for each direction is assigned based on the magnitude of its directional derivative
