Abstract
A method for interpolation includes receiving an input image having a plurality of pixels and estimating an edge direction proximate a first pixel of the input image using a first technique from a plurality of discrete potential directions. Interpolating pixels using a substantially arbitrary scaling factor proximate the first pixel based upon the estimated edge direction and interpolating pixels using substantially arbitrary scaling factor proximate the first pixel based upon another technique not based upon the estimated edge direction. The interpolated pixels are determined for an output image having more pixels than the input image based upon the interpolated pixels of step (c) and step (d).

A method for interpolation comprising:
- (a) receiving an input image having a plurality of pixels;
- (b) estimating an edge direction proximate a first pixel of said input image using a first technique from a plurality of discrete potential directions;
- (c) interpolating pixels using a substantially arbitrary scaling factor proximate said first pixel based upon said estimated edge direction;
- (d) another interpolating pixels using substantially arbitrary scaling factor proximate said first pixel based upon another technique not based upon said estimated edge direction;
- (e) determining interpolated pixels for an output image having more pixels than said input image based upon said interpolated pixels of step (c) and step (d).
