Abstract
A method for image scaling. Specifically, one embodiment of the present invention discloses a method for image scaling that begins by selecting an input pixel from a first image. An input edge characteristic is determined from an input window associated with the input pixel. The input edge characteristic is determined from a plurality of predetermined edge characteristics that are associated with sets of filter coefficient vectors. An output window is generated by filtering the input window with a corresponding set of filter coefficients associated with the input edge characteristic. An output image is generated by repeating the above for a plurality of input pixels associated with the first image.
