Claim One:
1. 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 potential directions; (c) selecting an edge direction based upon said estimating said edge direction proximate said first pixel of said input image using a second technique; (d) interpolating pixels proximate said first pixel based upon said selected edge direction; (e) interpolating pixels proximate said first pixel based upon another technique; (f) determining interpolated pixels for an output image having more pixels than said input image based upon at least one selected from step (d) and/or step (e); (g) wherein said another technique includes a set of filters based upon a low-resolution data set and a high-resolution data set suitable for interpolating said input image, wherein said filters are collectively representative of at least a portion of an image space and a substantial number of said filters are representative of a different at least one selected from a volume and/or a shape within said image space, and said interpolating pixels proximate said first pixels based upon said another technique is based upon said filters.
